ms_clip() returns "Error: SyntaxError: Unexpected token ." #159

Closed lewkrr closed 1 year ago

lewkrr commented 1 year ago

Whenever I attempt to use the ms_clip(), I get the message "Error: SyntaxError: Unexpected token ." I even ran the Examples code directly from the documentation, and I still get the same error message.

Below is my session info. Please advise if there is an fix. Cheers!

Here is the traceback given by the documentation's example, in case it's helpful.
