C3W1_Assignment Upload Button missing

When the grader is trying to parse the output of the tokenize_labels an UNEXPECTED ERROR occurs saying that the output of that code block is too long.
The ERROR Details ask me to search here if anyone has/had the same problem.
I didn’t find anyone till now, but might be someone can help.
Thanks
