Some users can't log in

System Information
  • Strapi Version: v4.11.7
  • Operating System: ubuntu
  • Database: postgres
  • Node Version: v18.3.0

There are two users (not strapi users, users-permissions’ users)
e.g. one has a username “max-of-smith” with an email “
They are confirmed, not blocked and they have the role “Authenticated”
For my life, whatever I change their passwords to, when the frontend sends their data to strapi I get a 400 with the message “invalid identifier or password”

There are no weird characters in their email or username, neither in the passwords (I tried my own and I can log in just fine)

Has somebody experienced this before? And what was Your fix?

Had the same issue. Problem was is that, for some reason, some users had null as provider. I had to fix these users by setting provider: ‘local’ for them.
