Dapr Azure Storage Queue input binding could not invoke OPTIONS method on input binding subscription endpoint - azure-storage-queues

Question

I have followed the Dapr docs and am trying to set up an azure storage queue input binding for a dotnet 6 webapi project. The webapi project works as expected when run locally but when run through dapr fails to initialze and exist with the following error. Because Dapr issues an options method ond the binding endpoint I have includeded a options endpoint of my own. I have also added cors support (commented ot now). But nothing seems to help. Has anyone encountered this before. All help welcomed.
"could not invoke OPTIONS method on input binding subscription endpoint \"Process\": %!w(*errors.errorString=&{the server closed connection before returning the first response byte. Make sure the server returns 'Connection: close' response header before closing the connection})"

Answer 1

I had the same problem. The only thing I changed was my "applicationUrl" on launchSettings.json.
I just changed from 'https' to 'http' and it worked.

Answer 2

The problem was one of connectivity. The web app was not accessible in the exposed port. The options endpoints are required (webapi does not seem to add options endpoints to defined endpoints) and the UseHttpsRedirection method needed removing.
