Cannot Run Sonnet 3.7 Natively [REQUIRES UPDATE]

[cryptoguard]

What happened?

Hello,

It seems I am not able to run any Claude Sonnet 3.7 when natively using their API. Claude Sonnet 3.5 works fine, and 3.7 works fine when using it via OpenRouter.

Error I get:

Something went wrong. Here's the specific error message we encountered: Operation failed after 3 attempts: 400 {"type":"error","error":{"type":"invalid_request_error","message":"prompt: Input should be a valid string"}}

I'm using the Docker version of LibreChat self-hosted on a VM. The docker image is up-to-date as of this writing. I've added both model versions to my .env file, that is to say, both claude-3-7-sonnet-20250219 and claude-3-7-sonnet-latest. Neither work.

Thanks
