I've checked PAT tokens and they are fine. I've also looked for a project in source org with that ID and nothing exists. I've tried adding mappings to area and iteration but thats not working either. Ive attached my config file below. Please help.

configuration copy 6.json

Have you done what the error message asks?

This is usually due to TFS having a different installed langauge version than was expected.. Validate that 'Area' is the correct name in your version. This would be something like 'Fläche' or 'Aire'. If you open the area tree in Visual Studio, or web access, you should see the name your langauage uses for 'Area' or 'Iteration. Do not try to add a specific area or iteration path to this field.

[MrHinsh]

if your source server is german you might have something like:

"LanguageMaps": {
          "AreaPath": "GermanForArea",
          "IterationPath": "GermanForIteration"
        },

I was facing a similar issue and could trace it back to incorrect permissions of the access token. this in turns throws an 401 exception when parsing the node structure of the server/devops services endpoint

[MrHinsh]

Invorect permissions for the access tokens will do wacky things... always check permissions...

For me I got this error when I was pointing my target URL at the wrong collection. The error seems to be a bit of an unintended red herring.

[MrHinsh]

I'm looking into this... it may be that the collection is created within the context that I'm not expecting...
