Visual Studio Load Test – Could not read result repository

Issue

After running a web test, you see an error such as this:

Error message:

Could not read result repository: Unknown transaction id in results: XX.

Will display the runtime result instead of the repository result.

You also get a similar error when you try to load historical results from the “Open and Managed Load Test Results” screen. In my case, I am running Visual Studio 2015 with Update 3. The controller and agents are 2013 with update 5.

Solution / Workaround

  1. Open the load test file
