Anything else?

• The issue doesn't happen if you set http-accept-non-normalized-paths to true.
• The cause of the issue is that the UI code calls the REST API {{/auth/admin/realms/ {realmId}

  /clients/

  {clientId}

  /authz/resource-server/policy/

  {policyType}

  /

  {policyId}

  }} with empty policyType which results in double slashes in the URL.

• After checking the code, in ResourcesPolicySelect.tsx calls findOnePolicy() with empty type here.
