New web data source suddenly appeared in settings for Dataflow Gen1, cannot be authenticated

[KaterinaB]

We have many dataflows Gen1 (we dont have a Fabric license and will not get it any time soon) upon which we rely pretty heavily in our reporting structure. Some of these dataflows have the settings created with a service user (Windows account created for gateway connection, password never expires, is only used for Power BI Service purpose, is not used in business anywhere else), also the data source credentials are authenticated with this user's credentials. This has been running without issues for a long time, suddenly yesterday in some of the dataflows' setting a new data source appeared "Web", which then fails to connect. There is NO actual web data source in any of the dataflows.

When shown in lineage view, I see that this web link leads to a OneDrive account of this service user with a message that we cannot edit files because the license to use OneDrive ended and to contact our IT to assign by xxx date (the date changes, yesterday it showed yesterday's date, today today's date)

According to our IT support the user has a license and there is no history of removing it.

Does anyone experience something similar? What has OneDrive have to do with the Power BI authentication? And how can we get rid of that data source?
I have found this thread https://community.fabric.microsoft.com/t5/Service/Dataflow-shows-connection-to-Web-data-source-when-...  however we cannot use the solution of exporting .json and then creating the dataflow anew because that would mean having to change the dataflow ID in all related reports, that is not manageable. 
For now we have taken the not yet affected dataflows over with a normal user and the affected ones we did the json export and recreate.

Hi @KaterinaB ,

I have seen similar kind of issue in one of our dataflow. Open your dataflow and check all your queries and parameters. In our case we have a parameter with datamart, and we have deleted it after analysing all queries.

I hope this helps.

Thanks,

The issue was not solved yet. We have discovered that the affected dataflows do refresh despite the web source not being able to authenticate. Microsoft for now cannot reproduce the error and has no solution as of now

I accept that as a solution, just so that you will step messaging about it. We clearly did not get any solution yet, we have no clue where the data source came from and what caused it

Not sure what do you mean with "solution provided for the issue worked"? The suggestion below to open a ticket is a good one, but it is not a solution. We opened the ticket with MS and are waiting for feedback.
