Hey there @LLXP!
Can you help me understand your setup? Did you create a developer account with Okta? (like through developer.okta.com)? If so, you’ll have a custom authorization server requiring the JWKS. Or did you create your Okta org through different means?
Does this response from @andrea help?
If that isn’t your setup (or if you run into trouble identifying the authorization server to use or creating the JWKS), please let us know!
