invalid format: unclosed quotes

Error message

invalid format: unclosed quotes

What it means

At end of input ParseLogFmt is still inside an unterminated quoted value (inQuotes true when the scan finishes). The value's opening '"' was never closed, so the pair cannot be committed and the whole line fails to parse.

Solutions

1. Close the quote in the source log line, e.g. msg="hello world".
2. If quotes are unintended, remove them so the value is parsed as a plain token.
3. If upstream may emit unclosed quotes, catch this error and fall back to treating the line as a plain text log entry.
