Occasionally when downloading a chat response the file content just contains the error message in JSON format (independent of the download type: DOCX, RTF and MD), even though the download process doesn't indicate any error:
{"error": "Invalid chat turn index: 1. The chat has fewer turns even after retrying."}
There is no error popup or anything else to alert the user, that there was a problem and that generated file does not have the expected content!
