Getting error when trying to enable Free Microsoft Store Addins

I am just trying to enable the grave addon for minecraft bedrock. I am getting this error in the log.

I have copied the world from my local windows machine to the server. I am unsure as to why this doesnt work as ive added the required folders to the MC docker volume.

yeah, weird thing is, when i remove the content it works as expected. So i think its something to do with how it handles add-ons (premium paid ones)

I have the same problem.
I'm not sure what the right place for the addon is on the server. I've tried several locations in my mapped data volume of the container:
.../_data/behavior_packs/
.../_data/premium_cache/behavior_packs/
.../_data/worlds/Bedrock level/behavior_packs/
No luck yet. As soon as I remove the world_behavior_packs.json it works fine, but without the addon.
