Additionally, the workflow runs fine on my desktop but the issue arises only when I run it on the sever. The file connection for both is same and the server can access the file connection. When i try to access the table created, I get following error (Alteryx and Databricks)-

Hi Andrew, Thanks for the reply. 

It turned out to be an issue with one of the drivers on the server. Sorry for the delayed reply, I didnt log into my alteryx acc since last few months.
