ApiResponseError when opening any Dataflow

[rvp_ordix]

When opening any of my dataflows I get the following error message:

ApiResponseError: Unable to complete the request. Please retry again later, and if this issue recurs, check your network, proxy, vpn, or firewall configuration or contact your network administrator.

Most of the other forum posts about this point towards Gateways and on-prem data storages as the culprit but I use neither. All my tables are either on an Azure SQL Server in the cloud or in a Fabric Lakehouse. The message suddenly appeared one day without my having changed something.

Do you by any chance have the ublock chrome extension? There's been an update on that extension which blocks some APIs Dataflow Editor uses. Can you disable the extension and try again?

It was the Edge Version of that extension, but yeah, that worked. Somewhat strange, though, that this only became a problem recently. I've been using uBlock on Edge for months now without trouble. No matter. Thank you!

That was it! I had the same issue and disabling ublock fixed it.
