Common Causes of JSON Parse Errors
Syntax Errors
All keys and string values must be enclosed in double quotes.
There should be no trailing commas.
Proper use of colons and commas to separate keys and values.
Example of Syntax Error:
[[See Video to Reveal this Text or Code Snippet]]
The trailing comma after "express": "^4.17.1" should be removed.
Missing or Extra Brackets
Another common issue is missing or extra curly braces {} and square brackets []. JSON objects should start with { and end with }, and arrays should start with [ and end with ].
Example:
