Failure to download a file before running my workflow

[devoln]

When I run my workflow comfy-workflow-api.json on Replicate using version d485be22dbc, I get an error:

Prediction failed.

Command '['pget', '--log-level', 'warn', '-xf', 'https://weights.replicate.delivery/default/comfy-ui/facedetection/detection_Resnet50_Final.pth.tar', '/srv/r8/monobase/monobase/g00012/python3.10-torch2.5.1-cu121/lib/python3.10/site-packages/facexlib/weights']' returned non-zero exit status 1.

Logs:

⏳ Downloading detection_Resnet50_Final.pth to /srv/r8/monobase/monobase/g00012/python3.10-torch2.5.1-cu121/lib/python3.10/site-packages/facexlib/weights

I guess that tjis dependency on detection_Resnet50_Final is added by one of the PULID nodes that I use with FLUX. If I remove PULID nodes from my workflow, it works. Actually, I don't understand the error. The file URL is accessible, I can download it manually.

I encountered the same problem. i don't know why it download detection_Resnet50_Final.pth to a special path (which is read only)
