Howdy y'all,
We currently have a shared list setup which has multiple users, however one of our users regularly gets this error when opening the list - Something went wrong: Invalid argument: 'header's missing application ID header. He states he simply opens the list and the error populates, refreshing a few times fixes it.
For some reason I can't attach a image. But all it states is the error above with a spilt ice cream cone.
Thank you for any assistance.

Having this issue too - is there a fix. I keep seeing that Microsoft haven't seen this issue, but we are all reporting it. Is there a fix?
Yes, flows are not working properly. This is a huge problem for anyone using power automate with lists.
Unfortunately, the issue is still there. Refreshing the page certainly brings it all back.
I'm in the middle of developing some Power Automate flows that work on some lists, but I'm getting some unusual behavior. Now, some of that is me learning to use PA, but I noticed that the List was not updating correctly, despite my flow history indicating that steps had been carried out correctly.
Could this also be due to the problem being reported here?
I have many sites without Teams channels. (sign)
Today all the lists in the site I was working on started showing the 'missing header' issues as has been reported.
Quickly tried this trick on my troublesome site and it does seem to have cleared the issue for me. Will keep an eye on it.
