Complaint: ALB OIDC JWTs Invalid

I've implemented auth on ALB per

https://docs.aws.amazon.com/elasticloadbalancing/latest/application/listener-authenticate-users.html

The doc calls out "Note that standard libraries are not compatible with padding that is included in the Application Load Balancer authentication token in JWT format."

I just have to wonder why the hell this is; why implement something that doesn't conform to spec. I can validate with pyjwt, but nothing else that follows spec e.g. jwt.io, or noedjs middleware.

Anyone know of node libraries that are more forgiving like the pyjwt one?
