'Invalid body indentation level (expecting an indentation level of at least 4)

I just upgraded to PHP 7.3 and I'm getting this error:

Invalid body indentation level (expecting an indentation level of at least 4)

Here is the code:

    $html = <<<HTML
<html>
<body>
    HTML test
</body>
</html>
HTML;

Had similar issue the indentation of the closing "output;" was an issue. Leave no space on the left.

    $html = <<<HTML
      <html>
       <body>
         HTML test
       </body>
      </html>
    OUTPUT;        // leave no space on the left before the code
    echo $html;
    }
