Chat button remains unresponsive in workflows using AI Agent node

Based on your report it seems that nothing is showing up as an error message – the chat button just remains unresponsive rather than outputting an error. In cases like this with the AI Agent node, the most common causes are configuration issues rather than the node actively throwing an error message.

Here are some troubleshooting steps to consider:

1. Ensure Required Sub-Nodes Are Connected
   The AI Agent node is a cluster node that depends on additional sub-nodes (like a Chat Model or Memory node) for full functionality. If these aren’t connected, the chat button might not work as expected.
   • Make sure to click the + Chat Model button (or connector) to add a Chat Model sub-node.

2. Check for Prompt Configuration
   If you’re using prompt options (e.g. “Take from previous node automatically”), ensure that a valid prompt value is available. A missing or null prompt value might not generate an error message immediately but can cause unexpected behavior with the chat functionality.

3. Review Workflow Setup
   Although you indicated “NA” for workflow output and no error message is shown, double-check that you’ve created the workflow with a valid trigger (such as a Chat Trigger node) and proper connections between nodes.
   Often the discovery of configuration details (like ensuring credentials are set on the Chat Model node) can resolve the issue.

Since you’re not seeing any error message, the issue is most likely due to the workflow configuration. Adjusting your AI Agent node to include all required sub-nodes and valid prompt values should resolve the chat button issue.

If the problem persists, please share more details about your workflow configuration (redacting any sensitive information) so we can assist more specifically.
