This error for me occured when I was copying scripts and using blank queries.
This is not my image, not my database, so don’t try to access it, please 😀 I found it in Internet to illustrate the point.

This message is a little bit a lot not helping. If you deploy something to PROD at night it is also very stressful. So what do we do?
We start here: https://docs.microsoft.com/en-us/azure/azure-portal/capture-browser-trace
This is to try to capture a little bit more info before we ended up contacting Microsoft support.
I was supper lucky, if it’s the right thing to say in the current situation.
After my error appeared again, I click on Developer Tools in my browser (Ctrl+Shift+I) and did a little bit of recording on the Network tab. Pressed Create button again. Got the real error.
Mine was like this:
{“error”:{“code”:101200,”message”:”Invalid Cdm model Format”,”details”:”Name of ‘Attribute’ cannot contain leading or trailing blank spaces or consist only of whitespace.”}}
I don’t know where did that white space come from. But we founded it and fixed it at the end.
Happy days!
Do you have any more details on how you found and fixed the white space? I replaced the white space in my column names by trimming them and replacing spaced between characters with underscores. Starting to lose my sanity over this!
