Swagger Internal Server 500 Error #7227 | Support Center

ervingayle created 5 years ago

I recently upgraded from v5.0 to v7.0 and it was quite a task. Everything seems to be loading fine. However swagger is giving me an error and I cannot figure out how to fix it. The contents of teh Logs.txt file is below: System.ArgumentException: Type provided must be an Enum.

I can't reproduce the problem you mentioned above with the demo project of Zero v7.0. You can download the Zero Demo project to check it out.

I did download the aspnetzero v7 zip file about a week ago and I did file compares. So while I believe the original zip works my solution is not working. Is there something else I can do to troubleshoot?

Problem found - had a helper app service that had a public access modifier. Not sure why it caused it to bomb, but fixed when corrected to internal.
