No update... is infuriating... not sure if we've cracked first level support yet...  apparently with the engineers, but have had no sensible response.

It's actually unusable like this.

I had the same error 18 hours ago just one time. But now it works fine again.

I didn't change anything in the flow.

Strange.....

@Masor : Has the failed execution automatically been retried at a later point or did it fail without retry but the flow kept working afterwards for new events?

the flow kept working afterwards for new events a few hours later.

Same experience as @Masor the error appeared yesterday on a number of flows but I've since been able to successfully run them now and the error has gone.  It looks like a token expiry issue, in my case the account running the flows is MFA enabled so it might be something relating to that (normally is).

Same issue here since today, with some of our flows, not all of them.  Trigger = 'when an item is created or modified' in a sharepoint list.  

Since these flows are live, very frustrating!

Same Problem here. Creating a new trigger doesn't help.
