Installing Visual Studio 2013 Update 5 on a TFS Application Tier can break the web access if TFS 2013 update 5 is not installed.

  • Article

Having client software on a dedicated application tier is not advisable, and its proven to cause unwanted service breakdowns, here is a scenario which happens if you have Visual Studio 2013 installed on the app tier for TFS 2013 and if the Visual studio 2013 is updated to update 5 before upgrading TFS 2013 to Update 5. I am not sure if this can happen on any other update level, as far as I have tested its only on Visual studio 2013.5 and TFS 2013.4.

Errors:

You will the following errors when you click on backlog board, Queries etc in Web access:

"TF400898" An Internal Error Occurred. ( this is a very generic error, don’t get carried away, read on)

Error(s):

Cannot read property 'setMessage' of null

TypeError: Cannot read property 'setMessage' of null
