🐛 Bug: Error: This operation was aborted

[rambir4git]

♻️ Reproduction Steps

1. const { isLoading } = useCopilotChatInternal();
2. const { setThreadId } = useCopilotContext();
3. when agent is running ie isLoading == true, and a new thread id is set
   ...

✅ Expected Behavior

It should suppress Abort error and gracefully recover

❌ Actual Behavior

An error appears in console; Uncaught (in promise) Error: This operation was aborted. Pointing to this line:594
throw new Error(structuredError.message);

𝌚 CopilotKit Version

1.10.6

📄 Logs (Optional)

[copilotkit-support-bot]

The codebase already includes mechanisms to handle abort errors gracefully when the thread ID is changed during loading.

Details

Built-in Abort Error Handling

Automatic Abort Controller Management

• When a new chat completion starts (including thread ID changes), a new AbortController is created at line 335:

chatAbortControllerRef.current = new AbortController();

• Previous operations are automatically aborted when the thread ID changes during loading, as the existing abort controller is replaced.

Runtime Client Error Suppression

• The CopilotRuntimeClient.ts file has logic to suppress abort errors (lines 131-138):

// Abort errors are suppressed with console.warn("Abort error suppressed")
// Stream continues gracefully if there's no next item

• Specific abort errors are handled differently; some are allowed to pass through while others are suppressed (lines 51-56).

Action Execution Protection

• Action execution (lines 1098-1105) uses Promise.race to handle abort scenarios gracefully:

// Returns "Operation was aborted by the user" message instead of throwing

Current Behavior Summary

• Thread ID changes during loading are already handled gracefully
• Abort errors are suppressed at the runtime client level
• No "This operation was aborted" errors should reach your application layer
• The system automatically cleans up previous operations when starting new ones

Note: The current implementation should already suppress abort errors as described. If you are still seeing "This operation was aborted" errors, this might indicate a different issue or a specific edge case not covered by the existing error handling.

Confidence: High - Based on direct source code analysis showing comprehensive abort error handling mechanisms.
