YOUR TASK:
Fix the issue where logError crashes when err is not an instance of Error.  RESPONSE FORMAT: 1. Short explanation (2–4 sentences) 2. A unified diff patch with file paths  RULES: - Modify ONLY the files shown. - Do NOT invent new files or functions unless the task requires it. - Follow the patterns and style used in the codebase. - Keep diffs minimal and safe.

=== Assistant: 1. ===
# Explanation
logError expects an Error instance, but callers may throw strings or custom objects.
To prevent crashes, safely normalize the value before logging.
The fix checks whether the argument is an Error and falls back to stringifying other types.
# Patch

<syntaxhighlight lang="diff">--- a/utils/logger.ts
+++ b/utils/logger.ts
 export function logError(error: Error) {
*  console.error('[ERROR]', error.message);
+  const message =
+    error instanceof Error
+      ? error.message
+      : typeof error === 'string'
+        ? error
+        : JSON.stringify(error);
+
+  console.error('[ERROR]', message);
 }
