I would like to add datapacks to my realm. From my research, the only way to do so is to download the world, and put the datapack file in the datapack folder of the singleplayer world, then re-upload. However, every time I do, I get error 500. Now I have read all the old threads about this problem and admins have marked them resolved as of last year. This is false. I have also tried the fix of leaving the datapack file zipped in the folder, as one user from 2019 suggested this worked. For me, this also produces error 500. I have tried repeatedly for nearly 5 hours now because each upload verification takes around 20 minutes before the error.
