`avn user create` failed with error 400

[procinger]

What happened?

According to the documentation, a new user should be created with this command.

avn user create john.doe@example.com --real-name "John Doe"

Unfortunately, I get the following error message - even if I replace John Doe with the correct data

ERROR	command failed: Error: {"errors":[{"message":"Invalid input: 'cf_turnstile_response' is a required property","status":400}],"message":"Invalid input: 'cf_turnstile_response' is a required property"}, status(<class 'int'>)=400

What did you expect to happen?

A 200/201 response / exit code 0 and the user was created

What else do we need to know?
