Error 'Reference to non-existent field 'imgId'.' when using the edgesDetectDL

HI there
I got the following error when trying to use the edgesDetectDL to detect edges on my images:
Error in edgesDetectDL (line 42)
"Reference to non-existent field 'imgId'."
Is there any solution?
Thank you.

Did you follow the instruction in README?

Yes, and I have compiled Piotr's two toolboxes.

Seems that you did not load the "model".
