Hi,
I do apologise if this is duplicate threat but couldnt find anything on forum that would suit my issue. I have a flow, Request Approval (everyone must approve) for a selected file. That runs via button,

My flow is a standard one however it cant be executed due to the mentioned in subject error:



It never worked to be honest and i was wondering..... what am i doing wrong?
Could you please advise?
Tomasz
