What does this code mean?

Code AADSTS90002 · An issue reported by Microsoft Entra ID.

Official explanation · Original text

InvalidTenantName - The tenant name wasn't found in the data store. Check to make sure you have the correct tenant ID. The application developer will receive this error if their app attempts to sign into a tenant that we cannot find. Often, this is because a cross-cloud app was used against the wrong cloud, or the developer attempted to sign in to a tenant derived from an email address, but the domain isn't registered.
