Issue- Last couple of days My bot is abruptly closing the chat

When user clicks on Find courses, my bot was working as expected, 3 days and was giving answer from the airtable. The context window is large, but it was working as expected. But now what is happening is when it is going to that route, abruptly it is failing without showing an error. Not sure what to do
