Suppress warnings in bun js for HTMLParseError using non-html markup

I am using bun (and a library called bun-plugin-html) to inject css and javascript and build a source html file to a target file.

The html is actually a Tumblr template so it uses handlebars/moustache-like syntax for variables.

Currently bun is clever enough that it complains about the markup not being valid.

It does seem to work and parse the file, but I would like to suppress these warnings in the console. I am assuming this is possible.

Although the file uses curly braces style syntax, it is not the same as an .hbs file (that seems to use the rewriter in a different way). Any pointers? Can’t seem to find much information online about this, but maybe it’s not a bun issue (hence the jsdom tag).

Here is an example

   <li class="post photo">
      {LinkOpenTag}
         <img src="{PhotoURL-500}" {block:HighRes}style="display:none"{/block:HighRes} />
             {block:HighRes}
                           ^
HTMLParseError: Specified <img> src '{PhotoURL-500}' does not exist!
