As the subject states, I've got about a dozen flows which are triggered from a button on a sharepoint list.
For a Selected Item > Get Item
Automate seems to be prefixing the ID number with '100000000' so ID 5 is pulled into the flow as 100000005, resulting in a 'Item not found' 404 error.
These flows have all been working for at least 6 months. The problem also seems intermittent and is present in multiple different lists on separate sites. Sometimes it gets the right id, sometimes not.
