@snehal.libra I just had support help me address my issue. The SPA was configured with POST for “Token Endpoint Authentication Method” (I didn’t set that, it was defaulted to POST when app was created). However, that seems to require Secret being passed. I had to change to Web Application, set the method to NONE, then changed it back to SPA and was able to get past the same 401 error. Hopefully that helps you as well.
