The body is null when there is a reference like #XYZ in the commit message body

Steps to Reproduce (for bugs)

Develop a local plugin like documented here: https://github.com/conventional-changelog/commitlint/blob/master/docs/reference-plugins.md#local-plugins So the config file starts like this:

module.exports = {
    parserPreset: 'conventional-changelog-conventionalcommits',
    rules: {
        'body-leading-blank': [RuleStatus.Warning, 'always'],
        'body-soft-max-line-length': [RuleStatus.Error, 'always'],
        'footer-leading-blank': [RuleStatus.Warning, 'always'],
        'footer-max-line-length': [RuleStatus.Error, 'always', 150],
        'header-max-length': [RuleStatus.Error, 'always', 50],
        'subject-full-stop': [RuleStatus.Error, 'never', '.'],
        'type-empty': [RuleStatus.Warning, 'never'],
        'type-space-after-colon': [RuleStatus.Error, 'always'],
        'subject-lowercase': [RuleStatus.Error, 'always'],
        'body-prose': [RuleStatus.Error, 'always'],
        'type-space-after-comma': [RuleStatus.Error, 'always'],
        'trailing-whitespace': [RuleStatus.Error, 'always'],
        'prefer-slash-over-backslash': [RuleStatus.Error, 'always'],
        'type-space-before-paren': [RuleStatus.Error, 'always'],
        'proper-issue-refs': [RuleStatus.Error, 'always'],
    },
    plugins: [
        {
            rules: {
                'proper-issue-refs': ({body}: {body:any}) => {
                    let offence = false;   
                    if (body !== null) {
                        let bodyStr = convertAnyToString(body, "body");
                        console.log(bodyStr)
                        bodyStr = removeAllCodeBlocks(bodyStr);
                        offence = includeHashtagRef(bodyStr);
                    }

                    return [
                        !offence,
                        `Please use full URLs instead of #XYZ refs.`
                    ];
                },


...

1. Run the plugin against a commit message like

"foo: this is only a title" + "\n\n" + "Bla blah bla #123.";

The body in the 'proper-issue-refs' rule becomes null. I found out commilint parser parses this commit in such a way that when there is a reference in the body it put the body information in a reference array like this:

    [
      {
        action: null,
        owner: null,
        repository: null,
        issue: '123',
        raw: 'Bla blah bla #123',
        prefix: '#'
      }
    ]

and the body argument becomes null. But I believe it shouldn't affect the body argument.

Current Behavior

The body argument is null when there is an issue reference like #XYZ in the commit message body.

Expected Behavior

The body argument shouldn't be null.

• cli
• core
