Getting this error. See screenshots below. Attempting to pull the etag from a temporary task (because its possible no tasks will be in the Plan I'm attempting to rename). Help!

Can you put etag value in double quotes and see if it helps? In short, wrap expression in double quotes?

Can you add a compose on top of this action and use expression @Odata.etag and see what it returns?

Ok this is really odd. Apparently when you use HTTP to get plan details it gives you the wrong etag, but when you use list groups it gives you the correct etag! That makes PERFECT sense Microsoft!

I am now getting a new error 409 "The attempted changes conflicted with already accepted changes. Read the latest state and resolve differences.". Starting a new thread for that error.

Can you accept this as a solution if your original question is resolved so that this thread can be closed?
