Failed to load API definition - value cannot be null #286

Open jaltenbernd opened 9 months ago

jaltenbernd commented 9 months ago

Getting the "Failed to load API definition" for my .NET 8 Azure Function Out-of-Process. For that, I have to use the library: Microsoft.Azure.Functions.Worker.Extensions.OpenApi instead of the Swagger pkg for WebAPIs.

My SwaggerEndPoint URL to the swagger.json file for this one API is correct. All my others APIs come up fine, but this is the only one I have as an Azure Function. Is that the issue? Too new?

The error log is:
