Current Behavior

I created a function which contains a file probe as output. When running the function, the function job succeeds, but I get an error when requesting the outputs via the api-server. More precisely I receive a return code 500. When investigating the logs of the api-server, the issue seems to stem from an exception in sqlalchemy, when trying to serialize a UUID.

Here's the study I used to create a function (this has been tested on master and staging):

Here's a snippet of the logs I see in the api-server

    |   File "/home/scu/.venv/lib/python3.11/site-packages/aio_pika/patterns/rpc.py", line 416, in call
    |     return await future
    |            ^^^^^^^^^^^^
    | servicelib.rabbitmq._errors.RPCServerError: While running method 'update_function_job_outputs' raised 'sqlalchemy.exc.StatementError': '(builtins.TypeError) Object of type UUID is not JSON serializable
    | [SQL: UPDATE funcapi_function_jobs SET outputs=%s, modified=now() WHERE funcapi_function_jobs.uuid = %s RETURNING funcapi_function_jobs.outputs]'
    |   File "/home/scu/.venv/lib/python3.11/site-packages/servicelib/rabbitmq/_rpc_router.py", line 55, in _wrapper
    |     return await func(*args, **kwargs)
    |            ^^^^^^^^^^^^^^^^^^^^^^^^^^^
