Known issues

gotchaflake8-json is a formatting reporter; it does not add new lint checks. To get JSON output, use the --format json flag when invoking flake8.

fix

Run flake8 with --format json (or configure in setup.cfg).

breakingVersions prior to 24.4.0 may have different behavior for nested violations. Always check the output schema if upgrading from an older version.

fix

Upgrade to 24.4.0 and adjust parsing if needed.

affects: <24.4.0

deprecatedUsing 'flake8-json' as a package name (hyphen) is deprecated; import using underscore: 'flake8_json'.

fix

Use 'from flake8_json import ...' instead of 'from flake8-json import ...'.
