Failed when upload new video

[phatberstromgg]

Hi @dolongbien, I have ran your project and it worked great. But when I add a new video, the webpage of that task is cracked while the other task still working well. The error is:
NoReverseMatch at /catalog/video-upload
Reverse for 'task_status' with arguments '('',)' not found. 1 pattern(s) tried: ['celery\-progress\/(?P<task_id>[\w-]+)/$']
Could you help me solved this. Thank you.
