@kapilkd13 What's your progress?

[kapilkd13]

Hi @mr-c This error was due to http link was given as input. #507 This PR addresses this issue also. I tested it on my local system and this workflow works after the http input PR. 😄

[mr-c]

Great! I forward to #507 being ready for merging

[kapilkd13]

A unit test is remaining though. I will try to add it tonight.

[mr-c]

Fixed by #507
