Unable to parse the smart list rule condition

[Shwetang]

Hi I am trying to activate a smart Campaign using Marketo API but getting following error : 

Unable to parse the smart list rule condition.

In my smart list, I have "3rd Party Activity is Triggered ". Same SC, I am able to activate via UI but through API it is giving error. Any idea on the issue ?

Were you able to figure this out? I'm seeing the same.
