I am trying to create renditions for a gif file using Gifsicle: Command-Line Animated GIFs  When I run the command in my terminal its works but when ran from inside the workflow (still on my local machine) it fails:

Command (in workflow): 

/usr/local/Cellar/gifsicle/1.90/bin/gifsicle ${filename} --resize 1680x1680 > cq5dam.web.1680.1680.gif

error.log:

*ERROR* [JobHandler: /etc/workflow/instances/server1/2017-11-29/update_asset_3:/content/dam/1000rendition/testgif.gif/jcr:content/renditions/original]

I have no idea why this is failing, the logging is not really helping. All help is appreciated, thanks in advance!

Apparently  ` > cq5dam.web.1680.1680.gif` is not allowed as part of the command as discussed here: https://stackoverflow.com/questions/43120035/processbuilder-failing-when-calling-a-system-command-where-runtime-exec-works. You can fix it by setting a redirectOutput on the builder but of course this is deeply nested into the workflow and is not easily changed.

    I am now able to create renditions using gifsicle using following commands in my step:

    cp ${filename} cq5dam.web.1680.1680.gif
    gifsicle --batch cq5dam.web.1680.1680.gif --resize 1680x1680
    cp ${filename} cq5dam.web.1024.1024.gif
    gifsicle --batch cq5dam.web.1024.1024.gif --resize 1024x1024
    cp ${filename} cq5dam.web.600.600.gif
    gifsicle --batch cq5dam.web.600.600.gif --resize 600x600
