SharePoint GetItem Issue

[JonathanB]

Scenario1

Trigger flow with a button

getitem (SharePoint)- parameters: list url, listname, id (specific id, e.g. 10)

Gives bad gateway

Scenario2

Trigger flow with a SharePoint trigger (e.g. when new item is created) in ANY list

Use getitem (SharePoint)- parameters: list url, listname, id (specific id, e.g. 10)

works fine

It is almost like the initial trigger sets up some environmental things even if not the same list as the getitem
