=== Assistant: Ah! ===
Ah! I see the error here. Let’s carefully break it down.

The error:

<syntaxhighlight>lua/entities/drgbase_nextbot/relationships.lua:524: bad argument #1 to 'upper' (string expected, got table)

</syntaxhighlight>

means that somewhere in relationships.lua on line 524, the string.upper() function is being called, but instead of receiving a string, it got a table. string.upper() only works on strings, not tables.

From the stack trace:

<syntaxhighlight>UpdateRelationshipWith - relationships.lua:524
UpdateRelationships - relationships.lua:483
...

</syntaxhighlight>

It seems like when a NextBot is spawned, the base tries to update relationships (friend/neutral/hostile/etc.), but the input is wrong.

===== In DRGBase, UpdateRelationshipWith expects a string representing a relationship type, e.g., "HATE", "LIKE", "NEUTRAL", etc. =====

If you passed a table instead, for example:

<syntaxhighlight lang="lua">local relation = { "HATE" }
bot:UpdateRelationshipWith(otherNPC, relation) -- ❌ wrong

</syntaxhighlight>

It will throw this error.

===== 1. Check what you pass to <code>UpdateRelationshipWith</code>. Make sure it’s a string, not a table. Example of correct usage: ``<code>lua bot:UpdateRelationshipWith(otherNPC, "HATE") <syntaxhighlight>2. If your code sometimes uses tables (e.g., multiple relationships), you need to loop over them: </syntaxhighlight>lua local relations = { "HATE", "DISLIKE" } for _, rel in ipairs(relations) do bot:UpdateRelationshipWith(otherNPC, rel) end <syntaxhighlight>3. Optional safety check inside DRGBase: If you want DRGBase itself to be safe against this, you can edit relationships.lua around line 524: </syntaxhighlight>lua if type(rel) == "string" then rel = string.upper(rel) else print("[DRGBase] Warning: relationship is not a string!", rel) return end </code>`<code> =====

✅ TL;DR: UpdateRelationshipWith is being given a table instead of a string. Pass a string like "HATE" or "LIKE" instead of { "HATE" }.

If you want, I can look at your </code>relationships.lua` snippet and patch it so it never errors even if someone accidentally passes a table. That usually fixes this crash completely.

Do you want me to do that?

=== User: i posted it to the creater of drg base ===
i posted it to the creater of drg base
he said
multiplayer bug, not sure what causes it yet, the nextbots still work
then i said but i seen it in sp and ig

=== Assistant: Ah, okay—this makes sense. ===
Ah, okay—this makes sense. 😅

Here’s what’s probably happening:

Even though the DRGBase dev mentioned it as a multiplayer bug, the underlying issue (a table being passed instead of a string) can still technically happen in singleplayer under some conditions, like:
* Spawning certain NPCs that have multiple default relationships stored as a table.
* Addons or custom scripts that modify or extend DRGBase’s relationship system.
* Race conditions or delayed initialization: sometimes the entity isn’t fully set up, and UpdateRelationshipWith gets a table by accident.

So even in SP, it’s possible to hit that same error.

The good news: as the dev said, NextBots still work—this is more of a warning/error in the console than a crash. It only happens when DRGBase tries to string.upper() something that isn’t a string.

If you want, I can give you a tiny local fix you can drop in SP that completely stops the error from spamming, without touching multiplayer compatibility.

Do you want me to do that?

=== Assistant: Perfect! ===
Perfect! Let’s make this thorough so your DRGBase creator friend has everything they need. I’ll give a safe patch and a full explanation of the issue, including context from your crash.

==== 1. The Issue ====
* Error:

<syntaxhighlight>lua/entities/drgbase_nextbot/relationships.lua:524: bad argument #1 to 'upper' (string expected, got table)

</syntaxhighlight>
* Cause: string.upper() is called on a table instead of a string.
* Function involved: UpdateRelationshipWith in relationships.lua.
* When it happens: Sometimes during NextBot spawning (SP or MP) when the relationship data is a table, not a string.
* Impact: NextBots continue to work; this is a console error only.

==== 2. Minimal Safe Patch ====

Edit lua/entities/drgbase_nextbot/relationships.lua around line 524. Wrap the string.upper call with a type check:

<syntaxhighlight lang="lua">-- Original line (approx)
rel = string.upper(rel)

-- Patched version
if type(rel) == "string" then
rel = string.upper(rel)
else
print("[DRGBase][Warning] Relationship is not a string!", rel)
return -- skip updating if invalid
end

</syntaxhighlight>

Explanation of the patch:
* type(rel) == "string" ensures we only call string.upper on strings.
* If rel is a table (or anything else), it prints a warning to console instead of throwing an error.
* return prevents the invalid value from breaking UpdateRelationshipWith.

✅ Safe for both Singleplayer and Multiplayer.
✅ Stops spam errors.
✅ NextBots continue functioning normally.

==== 3. Optional Improvement ====

If you want DRGBase to handle tables automatically (e.g., multiple relationships at once):

<syntaxhighlight lang="lua">if type(rel) == "table" then
for _, r in ipairs(rel) do
bot:UpdateRelationshipWith(otherNPC, r) -- recursive call with correct type
end
return
elseif type(rel) == "string" then
rel = string.upper(rel)
else
print("[DRGBase][Warning] Relationship is not a string!", rel)
return
end

</syntaxhighlight>

This way, any table of relationships will automatically be processed, preventing future similar issues.

==== 4. Why You Saw It in Singleplayer ====
* Some NextBots or mods might store relationships in a table by default, even in SP.
* Any addon or custom NPC might trigger the bug if it calls UpdateRelationshipWith with a table.
* DRGBase didn’t break SP functionality, so it’s easy to miss unless watching the console.

==== 5. TL;DR for the Creator ====

Summary you can send them:

: DRGBase throws bad argument #1 to 'upper' (string expected, got table) in UpdateRelationshipWith.
: The root cause is that string.upper() is called on a table instead of a string.
: Happens in SP and MP when a relationship is stored as a table (e.g., multiple default relationships, custom NPCs, or addon conflicts).
: NextBots still function, but the error spams the console.
: Suggested patch: type check before calling string.upper to safely skip or iterate tables.

If you want, I can also write the full modified <code>UpdateRelationshipWith</code> function ready to just drop in relationships.lua—so you don’t even have to patch line by line. This version would fully handle tables safely in SP and MP.

Do you want me to do that next?

=== Assistant: Great — thanks for sharing the link for the DrGBase | Nextbot Base mod. ===
Great — thanks for sharing the link for the DrGBase | Nextbot Base mod. Here is the full modified function for you and the creator, ready to drop into lua/entities/drgbase_nextbot/relationships.lua. You can paste this in place of the existing UpdateRelationshipWith (or patch it accordingly).

<syntaxhighlight lang="lua">-- In relationships.lua (around line 524 or where UpdateRelationshipWith is defined)

function ENT:UpdateRelationshipWith( target, rel )
if not IsValid( target ) then
return
end

-- If a table of relationships is passed, handle each
if type(rel) == "table" then
for _, r in ipairs( rel ) do
self:UpdateRelationshipWith( target, r )
end
return
end

-- Ensure we have a string
if type(rel) ~= "string" then
print( "[DRGBase][Warning] Relationship is not a string or table!", rel, target, debug.traceback() )
return
end

rel = string.upper( rel )

-- Continue original logic below...
-- (existing code in the function remains unchanged from here)

-- Example continuation:
-- local cur = self.Relations[ target ] or "NEUTRAL"
-- local newrel = rel
-- if cur == newrel then return end
-- self.Relations[ target ] = newrel
-- etc.
end

</syntaxhighlight>

===== ✅ What this patch does: =====
* If rel is a table, it loops through each element and calls the function recursively.
* If rel is not a string or table, it prints a warning with the value and target (and traceback for debugging) and exits safely.
* If rel is a string, it upper‑cases it safely and proceeds with the rest of the logic.
* Prevents the bad argument #1 to 'upper' (string expected, got table) crash.
* Keeps compatibility for both Singleplayer (SP) and Multiplayer (MP).

===== 📋 Info for the creator: =====
* Reported error: ``<code> lua/entities/drgbase_nextbot/relationships.lua:524: bad argument #1 to 'upper' (string expected, got table) </code>`` (Seen in SP and MP)
* Likely cause: UpdateRelationshipWith being passed a table instead of a string.
* Occurs when spawning nextbots that have relationship definitions as tables or via addons/custom scripts.
* Fix: add type‑check logic above and optionally support table input as shown.

You can copy‑paste this chat into your message to the mod creator so they have context + the patch ready. If you like, I can also format a full issue text (markdown) suitable for posting on the GitHub issues section of DrGBase. Would you like me to generate that?
