Problem after migration TFS 2010 to TFS 2017
I upgraded TFS from version 2010 -> TFS 2013 Update 5 -> to TFS 2017.3.1. The migration was successful, without errors.
When we select any work item we get error:
TF400898: An Internal Error Occurred.
{"message":"TF400898: An Internal Error Occurred.","type":"System.NullReferenceException"}

It looks like api can't read domain users who own the work item.
This is not a TFS cache issue because it has been cleared on the client and server.
It depends on the users. eg, TFS administrator does not have such an error, work item opens correctly.
What could be the reason for this error?
Authorizations have been checked many times. It's not helping. Unable to load user field, and EventViewer loops have: TF53010: The following error has occurred in a Team Foundation component or extension: Exception Message: Object reference not set to an instance of an object. (type NullReferenceException) Because the field is treated as empty.
Hi @Ebasse Thanks for your quick response. According to your error message, did you install any 3rd-party extensions which may cause this issue. Suggest you give a try with disabling them temporarily and check if this do the trick.
Besides, If the upgrade was successful without any errors. Then this kind of erorr may related to the configuration. You could try re-running the configuration wizard for the team project to fix the issue. How to please refer this tutorial: Configure features after an upgrade
I have disabled add-ons for the collection and no changes. Similarly, if reconfiguration is performed. The problem persists.
Disconnecting and reconnecting did not help. I re-graduated 2010 to 2017 without the following command and it seems to have helped. The question is why the problem is them: "TFSConfig ChangeServerID /SQLInstance:server_db /DatabaseName:TFS_Configuration". Maybe in the migration process before this command I should use an additional command. What do you think?
