API registration throws a 400 error - Token is not defined

I have a problem registering a new user via the API (auth/local/register)

When I submit the request, I get a 400 error saying “TOKEN is not defined”.

Which token is meant here? The user will receive a confirmation email that includes the link to confirm their account. Is the confirmation token meant? How should I pass it?

Thanks for your help!
