If you can resolve this issue , kindly help. Regards,

Do you have the JEP Python library installed? What does the config of the Python component look like?

The Exception means that the Java dependencies for JEP can't be found, which I got when JEP in Python was missing

ishaansharma commented 3 years ago

I installed the JEP from the source using the steps mentioned in this repository. Requirement already satisfied: jep in /home/<user>/anaconda3/lib/python3.8/site-packages (3.9.1) python path: /home//anaconda3/bin/python3.8 script Path :/home//Talend/workspace/pt.py When I am trying to guess the schema, than also it is showing the above error. I went through this but still couldn't resolve the issue. Regards,
