Call to a member function id() on string in Drupal\context\ContextManager->getContext()

Thanks for the patch. It would be good to get more explicit steps to reproduce so tagging. Switching this to the 5.x branch as that is the latest release though it can be back ported.

Addressed #8 please review.

Pardon me, but I am on branch 5.x but when I visit the path to add a field-group, I am getting permission errors.
Please assist me in reproducing this on 5.x so that i can apply patches in it.
Please & Thank You.

I was not able to reproduce this issue on the 5.x branch when using field_group module version 3.6.0 and Drupal version 9.5.11.
