Hey there.
Sometimes this error is linked to MFA, but you can also run into issues if you have Conditional Access in Microsoft Entra ID turned on.
However, if the problem is linked to MFA, your only options will be to either disable it on a service account or creating an organization manually, which will generally mean more manual setup work on each new project.
A token is also required not only for the integration (and project onboarding) but to perform PR decoration. There’s no workaround for this. I highly reccomend disabling MFA for a single user.
