Tool error - Unable to finish job with no messages of tool execution generated

Hi everyone! Our lab is using galaxy for a data analysis pipeline. Recently, we noticed that there’s a new tool named FEAST (https://github.com/kant/FEAST) and I intend to add this tool to our galaxy. During this process, this error occurred. In my local test, everything is good with the R code that the author provides, but in test run on the server of our lab, the result shows tool error & Unable to finish job. In the Dataset Error page, it says "An error occurred while running the tool FEAST. Tool execution generated the following messages and what is following is nothing. This makes me very confused to solve this problem.

If anyone encounters similar problems or understands what is going on here, please help me.

Any help will be appreciated! Many thanks!
