500 error code when calling published API to Azure:

Steps to create Api project (works locally):

• open Visual Studio 2022
• choose API project on windows
• weather forecast api project automatically generated, has Swagger integrated
• tested locally, works OK: https://localhost:7264/swagger/index.html // has a single get request, avalable at: https://localhost:7264/WeatherForecast

Steps to deploy to Azure:

• from VS, right click on project, Publish

• target = Azure

• Azure service used to host app: "Azure App Service (Windows)"

• choose subscription

• create new (App Service): give it a name (wfappservice), choose existing resource group, create hosting plan with Size S1.

• In the "Api Management" section - create new instance: WFA1api; API URL suffix: wf

• Go to Azure portal - RG selected earlier - find here the API Management created earlie i.e. WFA1api

• Inside the API Management service, choose APIs - choose the WFA1api instance - right click it - choose Import API - browse to the OpenAPI specification (json file downloaded earlier from the Swagger page from the local project) - click Import

• To test, go to the TEST tab (from the same API Management service instance) - click on the GET request (shows up here from the OpenAPI specification file imported on the previous step) - click on SEND on the request -> I get error 500:

{ "statusCode": 500, "message": "Internal server error", "activityId": "f773cfca-45a4-4a2f-b1ed-96d1ef2ef66f" }

On the TRACE tab, I see:

Trace is not available because response does not contain Ocp-Apim-Trace-Location header.

Any idea on how I can solve or debug this error? And how do I make the Api call if I skip the Api Management step, what is the procedure in that case? What if my project also has a database?

Thank you
