When adding a comment to a task I was met with an error, "You are not allowed to add a follower to this task," however after refreshing the page I my comment was posted. I originally noticed this after attempting to upload an image and write a small comment regarding it, at first attempt I was received said error and attempted again, receiving the same message. After refreshing the page, the comments had been posted, however no image had been uploaded. Regardless, there is some debugging that needs to be done. Perhaps this stems from a user without permission to post on certain tasks? I received the same error message after trying to add myself to this specific task (was a part before migration, however no longer after the update occurred).
