When making a call to the **A027**  **Convert advice and guidance request to referral** api, I am getting a 500 Internal Server Error in return but no accompanying message to indicate what the issue could be.

Is this an issue with the request I am sending, or is there an issue with the api endpoint?

I’ve confirmed all headers are present (I get a 4xx message if they are not) and the body content matches the schema in the api documentation.

This has previously worked.
