I am trying to validate my JWT token using jwk, the same way it is present in the documentation, but I keep receiving the error:

"undefined method `verify' for nil:NilClass"

Can someone help me?
I get my jwk from my keycloak server, and it is a hash, with the right format.

Looks like you are using version 1.5.6 of the gem. The JWK support was introduced in 2.2.0.

Also the latest released version expect the keys to be symbols. The next release will have support for a mix of strings and symbols. Until that you need to symbolize the keys in the hash given to the decode method.

Closing this. Please reopen if there are some issues with this and the latest versions of the GEM.
