Hi FusionAuth team, FA API has a weird behaviour when issuing JWT tokens.
Error example:
Firebase\JWT\SignatureInvalidException: Signature verification failed in /vendor/firebase/php-jwt/src/JWT.php:141
The setup is working well, but from time to time FA can generate an invalid access token. It happened 5 times over the weekend - rarely, but it does.
I use elliptic certificates, customers and guest JWT tokens and both were affected.
For the customers - I use lambda to fill custom claims, but for the guest - I use vend endpoint - so it's not related to the way to issue it.
Could you help me with it?
The invalid guest token:
