Unable to upload a map with datapack on, Whenever I upload the map/world gets uploaded without the datapack. I have tried the following

1) Uploading the datapack in existing map/world on realm

2) creating a new world  uploading it to realm and uploading the datapack to realm seperately after

3)Creating a new world applying the datapack testing it offline then uploading the world which is successfully running the datapack

4) Running the map with cheats on and experimental features on ( additional modding capabilities).
