The application uses azure keyvault for enviroment variables.

What i tried:

1. Asked for my azure user to be invited to the project.
2. My azure account has been granted owner rights.
3. Installed azure cli and used az login on vs code.
4. Added data reader rights on the key vault access control.
5. Added my user to access policies with the same permissions as the dev before me.

I also sure to log in on the azure account in visual studio code before i ran program. Also tried in regular visual studio for mac os, but had the same result.

Answer 1

I came accross this issue with the same error message. I could either call az loginprior to running the program

or I could call DefaultAzureCredential with the parameter includeInteractiveCredentials:true

var secretClient = new SecretClient(new Uri(keyVaultUri), new DefaultAzureCredential(includeInteractiveCredentials: true));

this opens a browser and tries to login the current user and enables the login.
