iControl Rest Transaction Commit Fails Due to Missing Transaction ID?

This error occurs when you attempt to commit a transaction that doesn't include any commands that create, modify, or delete an object on the F5. GET requests don't count towards the transaction command list.

There wasn't anything I remember seeing in the documentation about this and the error message had nothing at all to do with the issue, hence my confusion. Once I threw a few POST requests into the mix, the transaction went through.
