Team Export: MS-Graph Account Switch

Hi,

Searching for a utility to export channel content from Teams Free (Classic) to a readable format e.g. json or csv. Came across this three year old solution which looks pretty good. Following the instructions to login:

  Login to access your own data

• In the Sample Queries section on the left, click "show more samples"
• activate the "Microsoft Teams" collection of sample queries
• run the "my joined teams" query, view the results and copy the id value of the team that you want to export

the first issue is with the login account. The team organization I belong to is with a non-Live account B, in signing in with that ID (a registered MS account ID), get bounced straight away to my primary MS personal Live account A, which is not a member of any organization, or, in this case, org-wide team. Attempting to switch back to B gets the same behaviour.

This first issue could be a cause/consequence of any of the known graph issues, nevertheless, any methods of getting into graph with the desired account would be appreciated.

There was a prompt to login to an organization, and was able to provide the domain of it, things proceeded with account B for a little, but got then bounced to account A, with this error following a little later:

AADSTS70011: The provided request must include a 'scope' input parameter. The provided value for the input parameter 'scope' is not valid. The scope N/A openid profile offline_access is not valid. The scope format is invalid. Scope must be in a valid URI form https://example/scope or a valid Guid <guid/scope>.

The second issue is running my joined teams gets a privilege warning, and clicking the consent button on:

API.connectors.Read.All

API.connectors.ReadWrite.All

does nothing, as with any of the other items on the list below.

Any hope for MS.Graph in this scenario?

Thanks.
