Unterminated string

What it means

Every opening double quote needs a matching closing quote on the same line. A missing closing quote — or a line break inside the string — leaves it unterminated.

Example

{ "greeting": "hello }

{ "greeting": "hello" }

How to fix it

Add the closing double quote (and escape any real line breaks as \n).
