Steps to reproduce

After uploading an image, although the nodes can run, key fields are lost during the intermediate processing state of the image file. As a result, subsequent Understanding nodes cannot obtain actual readable image information, or Knowledge Base nodes fail to receive the parsed results. Symptoms include:
The Processor throws a path error
The Understanding node outputs empty content
The Knowledge Base appears to execute successfully but does not actually store data
