My Flows were working and today I open them and there is an error that reads 'Cannot read property 'toLowerCase' of undefined'. when I examine the flow there is nothing wrong with it, help please. This started today.

I'm having the same issue. I think it is to do with the Flow website, rather than the Flows themselves.

Related to the issue: I can no longer assign Flows to SharePoint lists, whereas I could do this on Friday (25th May).

Hi @Tumelo,

I have made a test on my side and don't have the issue that you mentioned. I agree with @Deck's thought almost, I think this issue is related to Flow website rather than Flow itself.

Please try it again on your side and check if the issue is solved on your side now. If the issue still exists, please let me know here, I would post this issue to my product team.

If this issue has been solved, please click the "Accept as Solution" button, so that this thread will be marked for other users to easily identify if your problem is solved.

Best regards,

Kris

It wasn't my original post, that's probably why I don't see it.
