Contentful This is not valid JSON

Question

I have the content model with one field as a JSON object. When I write an array inside this field I get This is not valid JSON .

Also in another screenshot, as you can see on Contentful Page it shows the error as mentioned above.

Answer 1

JSON does not allow a comma after the last element in an array:

Good:

 let string = '["Hello","Folks"]'; console.log(JSON.parse(string));

Bad:

 let string = '["Hello","Folks",]'; // comma after "Folks" console.log(JSON.parse(string));
