What did you do?

Configuration

const eslint = new ESLint({ fix: true, fixTypes: ['directive', 'problem', 'suggestion', 'layout'] });
const results = await eslint.lintText(page);

What did you expect to happen?

it's supposed to lint a string that looks like this :

output: 'const Index = props => {\n' +
      '  return (\n' +
      '    <>\n' +
      '      <style jsx global>{`\n' +
      '        #iv5w9l {\n' +
      '          margin: 0;\n' +
      '        }\n' +
      '\n' +
      '        .gjs-shape-divider > svg {\n' +
      '          height: 100%;\n' +
      '          width: 100%;\n' +
      '          transform: scaleY(-1);\n' +
      '        }\n' +
      '\n' +
      '        .gjs-shape-divider--fl-v > svg {\n' +
      '          transform: scaleY(1);\n' +
      '        }\n' +
      '\n' +
      '        .gjs-shape-divider--fl-h > svg {\n' +
      '          transform: scaleX(-1) scaleY(-1);\n' +
      '        }\n' +
      '\n' +
      '        .gjs-shape-divider--fl-v-h > svg {\n' +
      '          transform: scaleY(1) scaleX(-1);\n' +
      '        }\n' +
      '\n' +
      '        .gjs-shape-divider > svg > path {\n' +

      '\n' +
      '        .gjs-shape-divider > svg {\n' +
      '          height: 100%;\n' +

      '        }\n' +
      '\n' +
      '        .gjs-shape-divider--fl-h > svg {\n' +

      '        }\n' +
      '      `}</style>\n' +
      '      <div>\n' +
      '        <div id="iaemhv">\n' +
      '          <div class

What actually happened?

    ruleId: null,
    fatal: true,
    severity: 2,
    message: "Parsing error: The keyword 'const' is reserved",
    line: 1,

the default ecmaVersion is 5, you'll need to config it >=6, to use the features like let/const.
