Templating not working on new domain

I’m migrating an old project to Netlify. The code is identical, but on Netlify the templating is not working.

Here’s the code that shows my ‘hits’:

          container: "#search-results",
          cssClasses: {
            root: "results-wrapper",
            list: "emoji-wrapper",
            item: "emoji",
          templates: {
            item: `
     style="transform: translate3d(0px, 0px, 0px) scale3d(1, 1, 1) rotateX(0deg)
         rotateY(0deg) rotateZ(0deg) skew(0deg, 0deg);
       transform-style: preserve-3d;
     {{ symbol }}

For some reason, Algolia is not reading the symbol attribute from my dataset and shows empty search results.

Here’s the old link:

And the new link:

Appreciate any help!
