ALTINNAPP0001: Altinn app project not found

The analysis could not find the project directory and did not run

This diagnostic is reported when the analysis starts but cannot find the directory of the app project. The analysis then does not run, and the other rules say nothing about the app — in this case, the absence of other warnings does not mean that everything is fine.

Category General, severity warning.

The message asks you to contact support. That is the right response: this is not something you fix in the app code.
