[Vue warn]: Error in render: "SyntaxError: Unexpected end of JSON input"?

Question

Vue.js

Good evening!
An error occurs if there are TIMESTAMP columns in the table I query the database
, then I encode it in JSON
$pricesJSON = json_encode($prices);
I pass the parameter in the tag:
<order fuel_cost={{ $pricesJSON }}></order>
I decode it in VUE:
var obj = JSON.parse(this.fuel_cost);
Thank you!
