So you are able to search for the TEIs but you are not able to List TEIs when selecting the OU?
The error does say ‘no outree’ so it has to do with the permissions in the program access to OUs or maybe the user’s assigned OUs?
Are you able to see the list for other orgunits in another program? It would help if we can reproduce the issue on play and if we can’t then it might be a misconfiguration that we need to understand specific details.
Could you check which API requests are failing from the Network tab?
Thank you so much for your ideas, I have already done these things in Server IF I did not do that our Icons were not working and missed due to bootstrap. I found the Solutions it was very easy I forgot to select Display in List how it was showing the record.
