Hi!

In the latest version of python, the line (97, 128)

self.uid = urlsafe_base64_encode(force_bytes(user.pk)).decode() will error out.

It should be self.uid = urlsafe_base64_encode(force_bytes(user.pk)), since urlsafe_base64_encode(force_bytes(user.pk)) is already decoded.

Been following but now have 4 errors
AssertionError: None is not instance of SetPasswordForm —>“test_contains_form” (PasswordResetConfirmTests)
AssertionError: False is not True: Couldn’t find ‘href=/reset/‘ in response —> “test_html” (InvalidPasswordResetConfirmTests)
AssertionError: False is not True: Couldn’t find ‘csrfmiddlewaretoken’ in response —> “test_csrf” (PasswordResetConfirmTests)
AssertionError: 0 != 3 : Found 0 instances of ‘input’ in response —> “test_form_inputs” (PasswordResetConfirmTests)

HELP
Other tests work 💯
And there’s no error only 4 fails.

all the test are working correctly but i am getting two errors
