Smart Contract Testing - Issue with option(string)

Hi @dincho.chain,
Thanks for your reply.

  1. As you suggested to give {'None': []} (from javascript aesdk test )for the param which was defined as option(string) is still resulting in the following error. ValidationError: "Argument" at position 3 fails because [Value ""None":[]" at path: [3] not a string].

  2. giving undefined as input to the same param from aesdk works without any issue.

I am wondering why the former is still failing. Any thoughts.?
