Kotlin quiz: ""An error occurred when grading the quiz. Please try again"
I can't get my badges after completing my quizes. If I answer correctly the necessary amount of questions to pass the test and press "Submit answers" it displays the following message:

"An error occurred when grading the quiz. Please try again".

If I do the test again but answering incorrectly it show me my score.
