IndexError: list index out of range while executing a workflow including tiling+stitching

[Thomas]

Hi,
I am using chrome, and an object detection workflow including tiling and stitching (SAHI).
The workflow works flawlessly when called in the roboflow GUI.
However, when I call the

Executing command:
inference workflows process-images-directory -i F:\AI\RunPython\Input -o F:\AI\RunPython\Output -pt api --workspace_name ZZZZ --workflow_id YYYY-workflow --api-key XXXX --api_url http://localhost:9001 --threads 1 --debug_mode

Then the script

1. does the inference for each image
2. saves the image with the predictions to the output folder
3. saves a progress file with the 3 JPG images

until producing the following error:
“IndexError: list index out of range”

• **Project Type: object detection and count
• **Operating System & Browser: windows 10 + chrome

Any hints on getting the aggregation properly working would be very much appreciated.

thx & cheers
