Error: marker was not found when sending jpg path #18

I'm getting below error when saving a jpg image to disk and passing the file path to the coco node. Strangely it works the first time after starting the flow but after that the error occurs on every call. Any suggestions?

can you share a small example flow that shows how you are doing this ? Thanks
