Generating a Preview Image PrusaSlicer for Mac post-processing script issues! Please Help :)

[Vysper7]

I am trying to generate preview images for my Ender 3 S1 machine and am running PrusaSlicer on my Mac. My issue seems to be that I cannot get the post-processing to work. It really likes to send me this error:

This is the post processing script I use:
/usr/bin/python3 /Users/agentvinci/Library/Application\Support/PrusaSlicer/Scripts/CreateHeaderAndThumbnail.py;
I have also tried variations like this:
/usr/bin/python3\ /Users/agentvinci/Library/Application\Support/PrusaSlicer/Scripts/CreateHeaderAndThumbnail.py;
Or:
"/usr/bin/python3" "/Users/agentvinci/Library/Application\Support/PrusaSlicer/Scripts/CreateHeaderAndThumbnail.py"
But I can never get it to work.
I have python 3 installed on my Mac.
I have the Pillow library for python installed.
My .py script is correctly stored in PrusaSlicers Configuration Folder/Scripts
It has send me different errors in the past such as 126 or 127 but I think I got them sorted.
Please help
Thanks you so much,
Agent Vinci

Application\Support maybe should be Application/Support

Thank you for your suggestion but the folder is called 'Application Support' with a space between the words. I have found out the PrusaSlicer doesn't understand spaces and instead you have to show them with a '' character. Without this we get the 127 or 126 error I think.

Error 2 means that Python cannot find the script in the specified path. You can see in the error response that there isn't a space between Application and Support.

Ok I tried that and it worked! Now we have a different error though. It's saying the image results are too large and it cannot find a module named 'PIL'.

I don't have a MAC but it seems related to a missing library in your Python installation.

Thank you for the suggestion and your help. The Mac has python 3 installed with all the libraries. I have successfully used cura to generate thumbnail images. However, it turns out that the screen of the Ender 3 S1 doesn't support thumbnail images anyway if you have a DACAI screen (with was mentioned in the article) and so it turns out that I have a DACAI screen :(. PrusaSlicer still doesn't generate images but it doesn't really matter anymore since I switched back to the maybe slightly inferior but properly configured Creality Slicer (Cura skin) and am printing successfully though it. Thanks again for your support.
