Actions result in 500 error when trying to post

[im360john]

What happened?

when trying to post within agent actions, the attached openapi spec always returns a generic 500 error message. this is with latest librechat and using openai gpt-4o-mini model.

testaction.txt

When trying the same openapi spec within chatGPT, it works fine. Notably openai always asks if it should reach out to the destination URL.

The error output you provided is from the UI and not enough to help you.

Please paste relevant logs that were created when reproducing the error.

Log locations:

• Docker: Project root directory ./logs
• npm: ./api/logs

There are two types of logs that can help diagnose the issue:

• debug logs (debug-YYYY-MM-DD.log)
• error logs (error-YYYY-MM-DD.log)

Error logs contain exact stack traces and are especially helpful, but both can provide valuable information.

Please only include the relevant portions of logs that correspond to when you reproduced the error.

Also, for what it's worth, I would recommend restructuring the OpenAPI to use OAuth directly:

Or whichever authentication method would work for you
