Runtime Error 53 Running Shell Script Mac

I am trying to run a Shell script from Excel using VBA. The prompt which runs correctly in Terminal is

cat 'prompt.csv' | sh runScript.sh 'WSO'

. The following code attempts to run that line, but raises

Error 53: File Not Found

The notebook this script is attached to, prompt.csv, and runScript.sh files all live in the same folder. I am using Office 2016 for Mac. Any help is much appreciated.

Sub Run_Jar()
    ChDir ActiveWorkbook.Path
    Shell "cat 'prompt.csv' | sh runScript.sh 'WSO'"
End Sub
