PublicKeyCredentialSourceWebauthn::getRegistrationOptions() returns a Webauthn\PublicKeyCredentialCreationOptions object, which used to have a jsonSerialize method so, this line of code used to work:
return $this->webauthn->getRegistrationOptions($user)->jsonSerialize();
But with the latest changed I've updated it to:
json_encode($this->webauthn->getRegistrationOptions($user))
However json_encode returns false.
I've tried to step though and take a look but it's not obvious to me at this point what is failing.
A print_r of my $public_key_credential_creation_options shows:

Try json_encode output of getRegistrationOptions()
I'm not sure at this point.
I have seen the new serializePublicKeyCredential method but it doesn't accept PublicKeyCredentialCreationOptions (and doesn't appear to work if you hack it to remove that restriction.
Find cause of problem.

Sorry, I just saw this issue now. I'm assuming this is fixed by 🐛 webauthn-lib v5 removes jsonSerialize() Active ; if not, please feel free to re-open.
