How are you running it? Are you running func host start or dotnet run ?

I am running it from visual studio 2022, Here is the profile:

{ "profiles": { "DocuSignDocument.FunctionApp": { "commandName": "Project", "commandLineArgs": "--port 7278", "launchBrowser": false } } }

Looks like you are doing dotnet run. The function app payload should be started with the functions host (runtime). That is why the command to start is func host start. This will start the functions runtime and that will start your function app.

In short, you should not run dotnet run directly on your function app.

Had the same problem, it suddenly stopped working. I renamed the csproj file and kept everything else the same. Fixed it.
