Grade External Activity Xblock

Does Openfun Grade External Activity Xblock work with Juniper ? I used this fork and got the following error message in studio while enabling it.

WE'RE HAVING TROUBLE RENDERING YOUR COMPONENT Students will not be able to access this component. Re-edit your component to fix the error. Error: name 'unicode' is not defined

How can I resolve it ? Or is there any similar-alternate xblock with the same function ? I would like to grade an assignment that is not delivered through the Open edX platform.


Update : There is an edX “staff graded points” xblock available, which serves exactly the same purpose. It can be added from advanced problems.
