CachedKeySetwill cache thekeySetarray as-is and it cannot serialize theOpenSSLAsymmetricKeyobject contained in theFirebase\JWT\Keyobject. Because theOpenSSLAsymmetricKeyis not serializable, it fails validating tokens when result is retrieved from the cache with error:The proposed solution is to cache the JSON response from the JWKS endpoint. Because it's a string, it will not have any serialization issues. There will be probably some performance drawbacks, but I saw also that the class caches the result in memory.
