Hi @sneha ,
Can you attach screenshots of your plugin code environment on both your design and automation node?
Normally the code environment definitions would be the same (and have the same name) across both instances upon default creation of the code environment. If you do have multiple code environment definitions set up for the sentiment analysis plugin (for example you let's say you created one with Python27 and another with Python36), you could delete the "additional" definition and re-recreate the code environment definition with the correct Python version. If I am misunderstanding your setup, please do attach screenshots of your setup!
