Error: MoveItem failed

Good morning,
I use Render Manager with two stations, and with each job that uses the main station I get this error message associated with this station: “Error: MoveItem failed. Item with id ‘54b5ae01-f01b-4af3-a706-6a4c23ea1e9f’ not found”
And I have it even if I run a test job from the Setting page.
What does this error mean ?
