Not really an answer to the specific question, but if there are others, like me, who are getting this error in fastAPI and end up here:

It is probably because your route response has a value that can't be JSON serialised by jsonable_encoder. For me it was WKBElement: https://github.com/tiangolo/fastapi/issues/2366

Like in the issue, I ended up just removing the value from the output.
