Hi all
I've had a number of Gen1 dataflows working for months and they all still do work and refresh but I'm unable to add any new tables, I can't duplicate the ones I have or get to the SQL via source. Also tried creating new dataflows but I get the error. The first error is when I try to add a new table (or edit the source of an existing) then second is the message when I tried creating a new Gen2 dataflow. Any ideas on the issue??
Thanks for the responses. After two weeks the error has just spotted - unfortunatly we're not aware what has changed but now able to edit and add to dataflows as previously

Hello @CarrieG, thanks for posting to the community!
This error can be thrown when there are caching issues and/or an outdated browser. Here are some ideas you can try to resolve it:
Thanks for responding! I had cleared cache, tried other browsers and have tried incognito - all produce the same error. Was just waiting on my IT Dept to confirm but it doesn't appear to be a firewall issue either. This error is effecting everyone in my org who tries to edit/add to the dataflow.
Hi @CarrieG ,
Please consider reaching out to Microsoft Support. You can provide them with all the troubleshooting steps you've already taken, which will help them understand the issue better and provide a resolution.
