Invalid JWT Signature on OAuth OIDC Provider

[EduAr]

Hey there,

I'm attempting to retrieve data from my ServiceNow instance using a token generated by a custom identity provider. I've configured an OAuth OIDC Provider in my application, but I'm encountering this error when I make a request:

OIDC token verification failed: com.snc.platform.security.oauth.OAuthRequestProblemException: Invalid JWT Signature: com.snc.platform.security.oauth.jwt.AbstractJWTVerifier.verify(AbstractJWTVerifier.java:321)
