Alteryx App runs fine in Designer but fails in Server

Hello All,

I have an App that currently runs fine in designer but when scheduling in Gallery it fails. After many trials and errors with AYX support we were able to find one thing that we need to test to rule this out i.e. When the APP is running it creates PDF/PNG's in the folder where the APP is saved but for Server as it runs in the temporary engine space AYX told us that it could be that they python code that comes after the download tool step is unable to find the files PDF and PNG in the server directory where pythoon tool is looking as its because the files are created in engine space and python tool is looking in a directory specified by us so to tackle this we need to do 1)Either move the files from temp space to the directory we specified in python tool. or 2) Use the engine path in the python tool so that the code can look into the temp engine folder for PDF/ PNG and then do the post processing.

Is there a way I can use the temp path in the python code .

Hi @mohdfaraz47 !

You tried to run it from the designer in the server machine as well?

If yes and that runs ok from there, look if your server is configured to run as a different user, maybe that user don't have access to the path you're setting to get the image files.

Hello Marcus, Yes I did. Designer it works totally fine. Its only when its run from Gallery or when it is being scheduled. Any help is appreciated. We checked and the run as user has all the necessary permissions.

@mohdfaraz47 !

I see, try to add the installation code to your script. Maybe that package isn't installed in the run as user. If that fails to install, cehck your proxy settings in the server machine.

Yep we ensured that the correct libs are installed in the Server, That is not the issue. The error code when I run the app is as follows:
