Summary:

On the map Jumpscare Nightmares, when trying to install the content the map is never created after downloading it from the Marketplace. The player is able to purchase and download the content but when you select create world you get a splash screen that states “There was a problem loading this world” and the world save file is created but is unplayable. Once it breaks it says the world is only 1.7MB when in fact it should be around 45.7MB. The account we are using is a whitelisted account and we tried it on both my windows pc and the account holder's pc and we both had the same results. The Minecraft Cert team also tested it and they had no issues with it on the same builds as we had. We had to pull the content from the marketplace to keep customers from having a bad experience.

I had a previously saved world from the same template that I had sideloaded and when trying to play that one, I was given a large number of content log errors that filled up 12 pages on Google Doc (linked below). It's full of different content log errors but these ones are saying this on every file

“[Actor][error]-error parsing entity/jn/chandelier_boxes.entity.json:* Line 1, Column 1 Syntax error: value, object or array expected”

even though they are valid JSON files

It is worth noting that if you just install the world from our sidedloaded template, it works perfectly fine. The issues only occur once downloading it from the marketplace.

Impact:

Customers will be unable to play their purchased content from the marketplace

Repro Steps:
Purchase a copy of the map Jumpscare Nightmares from the Whitelisted Minecraft Marketplace

Download and install the content
Select create content to begin playing the map
The error should appear and the map will not load

Observed Results:

When selecting create content to begin playing the map the error “There was a problem loading this world” appears and the map will not load.

Expected Results:

When selecting create content to begin playing, the map the starts and I am jumpscared to heck and back.
