Hello everyone,
First of all, thank you for your help in advance!

Thanks,

In Transform Data, try clicking on 'Refresh Preview' for each query, i find that clears that error message when i get it.
You have a query that filters out some rows based on a key value that does not (or no longer) exist or that you no longer have access to. So you should try to find out what that non-existing key value is and then adjust your code accordingly.
Hi Adrian,
I don't know what causes them but most of the time, they disappear when you go to 'transform data' and check the query itself. It seems that just re-opening the query you created, solves the issue.
But I realize that it's a very time consuming thing to do when you have a lot of datasets.
Most of them, or basically all of them, look like this:
