vc-authn-oidc not working with ACA-Py 0.7.4-rc2 -- cannot create presentation request

[swcurran]

Trying to go through the demo/README.md instructions for the latest versions of ACA-Py. Things worked up through 0.7.4-rc1, but I'm getting an error creating the presentation request in 0.7.4.-rc2. I think the issue is fixed on main, but just wanted to have someone check it to be sure. The error on the screen is:

{"error":"acapy_call_failed","error_description":"Failed to create presentation request: Create presentation request failed: Code: [InternalServerError], Reason: [500 Internal Server Error\n\nServer got itself in trouble]"}

The ACA-Py log has this error:

@shaangill025 -- is this fixed in ACA-Py main? If not, could you please test this out? This is a high priority issue.

To test:

• follow the instructions in demo/README.py to run the demo. You have to wait for a bit (or just try several times) the curl step and when going to the django web page. It should work.
• Update the docker/docker-compose.yml file to use the 0.7.4-rc2 image for the aca-py instance. When you run it, you should get an error when you click the "Authenticate" button.

I suspect this is an error in ACA-Py, but if it is an incompatibility with the vc-authn-oidc controller, we need to know that and why.

Thanks!

This is likely solved by ACA-Py issue #1776. Attempting to test this now...
