MC Bedrock Edition: Commands including {components:json} end up not working.

     **     Hello Mojang devs! I have a command making issue. I was making a main room for a PvP map with special options through commands. One of those commands included a crossbow with the full proper {display} and enchant. First time I saw this because I just started making complex {components:json} commands as in /replaceitem and /give. The first time it failed. I thought this was because I was wrong in typing or had typos. I checked and changed a little bit of it but it still failed, but this time with this message (repeating this also for the fireworks that has similar structure to the crossbow.) :
