When Using Json in books, and lore doesn't allow spaces anymore.

I am trying to give myself a JSON book but it doesn't allow spaces. It gives me this error message:

[12:16:48] Data tag parsing failed: Expected '}' but got 'J' at: ...immediately!\"}]"],title:Precious J<--[HERE]

What this is referring to is the title of the book being Precious Jewels. It also affects the author name.
