body: <p>How to Assert OAM token in helidon using OIDC?</p>
  
  <p>I was trying to assert OAM token but getting error as shown below and I tried asserting IDCS token and it works fine</p>
  
  <pre><code>Exception in thread “main” io.helidon.common.Errors$ErrorMessagesException: [FATAL: Failed to load metadata: io.helidon.common.configurable.ResourceException: Failed to open stream to uri: https://{{OAM_host}}:{{port}}/.well-known/openid-configuration at io.helidon.common.configurable.ResourceException: Failed to open stream to uri: https://{{OAM_host}}:{{port}}/.well-known/openid-configuration, FATAL: When token_endpoint is not explicitly defined, the OIDC metadata must exist at class io.helidon.security.providers.oidc.common.OidcConfig$Builder, FATAL: When authorization_endpoint is not explicitly defined, the OIDC metadata must exist at class io.helidon.security.providers.oidc.common.OidcConfig$Builder, FATAL: When jwks_uri is not explicitly defined, the OIDC metadata must exist at class io.helidon.security.providers.oidc.common.OidcConfig$Builder]
  </code></pre>
  
  <p>And in the application.properties added OAM details:</p>
  
  <pre><code>providers:
      - abac:
      - oidc:
          client-id: "${ALIAS=security.properties.client-id}"

  <p>Am I missing something here?</p>
