JSON Missing Bracket
A missing bracket error means an object or array was started but not closed. The parser expects a matching closing brace or bracket.
Common causes
- Forgot to close an object } or array ].
- Extra opening bracket somewhere.
- Nested structure with one level not closed.
How to fix
- Count opening and closing braces and brackets; they must match.
- Use a code editor with bracket matching to spot the pair.
- Validate with an online JSON validator to see where the structure breaks.
FAQ
- How do I fix unclosed JSON?
- Add the missing } or ] so every { has a } and every [ has a ].
- Can one missing bracket break the whole file?
- Yes. The parser cannot know where the structure ends, so it fails.
