lti.Grade.submitScore() Error

Describe the bug When I try to update a line item using the Grade.submitScore() function, I get an error, it appears that the score object is not being created properly or I am missing fields.

    const result  = await lti.Grade.getLineItems(res.locals.token)

    let grade = {
        'scoreGiven': 83,
        'userId': 3,
    }
    
    await lti.Grade.submitScore(res.locals.token, result.lineItems[1].id, grade)

Expected behavior Update the given line item with the provided grade.

My pleasure! I would also like to state that i am working on the complete Grades Service documentation. I know it’s long overdue but this Service is by far the biggest and i didn’t have much time lately to focus on documenting it (specially since i was focused on adding new methods to make it’s usage more straight forward and flexible).

Thank you I was missing those fields!
