Error after importing user with custom password hash

[shagihan]

Once i imported users with a existing password, I’m always getting the following error message. Any reason for the issue?

This is fixed with correct password hash. If you get this error once the user bulk import, The reason could be imported user with an invalid custom password hash. It could be checked in logs.
