Thank you for the latest log @dharmesh13, it helped lead us towards finding that your issue you are experiencing with the Auth0 Authorization Extension is a ongoing challenge as detailed here in this Github issue:

If you could please answer the following questions here in this thread as well in the Github issue thread. It will allow us to further gain traction on eliminating this hurdle:

  • What version of the extension you are using?
  • What is your storage type (extension storage vs S3) and approximate storage size?
  • Could you share some metrics about your data? i.e. how many users, groups, roles, etc do you have?
  • What endpoints are causing the error? e.g. /policy , /login , group/roles management?

Thank you in advance!


@James.Morrison Here is the answers of questions of you and thank you for helping me :slight_smile:

  • Auth0 Authorization 2.4
  • extension storage
  • Total Users : 75, Groups: 3, roles:24
  • API endpoint /api/users/{auth_id}/roles


@James.Morrison, @jmangelo Have any updates?

Thank you


Hey @dharmesh13 thanks for following up, this issue is still on going and we don’t have a ETA for the fix as of yet. As soon as the Github Issue thread is updated we will have a better idea on how to move forward. Thanks!
