After I purchased a world with a behavior pack, “Mob Pets” (by Cyclone) I try to create to world and play it, when it is creating the world it says,

[Json][error]-Mob Pets | actor_definitions | /largedownload/premium_cache/world_templates/heHoXwo-BQA@/behavior_packs/bp0 | minecraft:parrot | minecraft:entity | components | Minecraft:can_fly | value | child ‘value’ not valid here.

Then it tries to load and says “Unable to connect to the world. Please check your connection to the internet and try again.” But it’s not supposed to be an online world, a realm or someone else’s world. Also, my internet is working even if I did need it. 

Please help, I don’t know what’s causing it and why that’s the only one that isn’t working. If I can’t play the world or use the behavior pack, I would like to have a refund of my Tokens back please. I have tried recreating the world and even deleting Minecraft from the PS4 and re downloading it. I really would like to play the world and would hate to have 990 Tokens used up on something that isn’t going to work. I feel sick that it isn’t working. Please help me.
 

Thank you so much.
