Error setting grade using ltijs

[jpsandovaln]

Describe the bug
When try to set grade an error is displayed

         const gradeObj = {
          userId: idtoken.user,
          scoreGiven: score,
          scoreMaximum: 100,
          activityProgress: 'Completed',
          gradingProgress: 'FullyGraded'}

        const responseGrade = await this.lti.Grade.submitScore(idtoken, lineItemId, gradeObj)

Reviewing the submitScore function the problem occurs in the following lines

const accessToken = await platform.platformAccessToken(scopes.join(' '));
the value for scopes is: const scopes = ['https://purl.imsglobal.org/spec/lti-ags/scope/score'];

Expected behavior
Set grade without issues
