I created a start node and input a image file. I need to get the image path in the disk(for example: /app/storage/upload_files/1687a316-96eb-4680-a09d-1e298b002afd/13fc29ad-b1d2-4516-a6b1-8dbf699f0ae4.jpg)
But in the input dict, I can't get the real filename. In the input dict, the filename is "614.jpg", but in the disk, the real filename is
"13fc29ad-b1d2-4516-a6b1-8dbf699f0ae4.jpg".
How can I get the real filename?
