Looking at the web page it seems you are using the builder web component to display dynamic builder content. Which seems to be missing modal="page" attribute, if so then mentioning the modal should fix the problem. Kindly check and let us know if you still have any further concerns. Thank you!
<builder-component model="page" api-key="YOUR_KEY">
<!-- HTML here will display while your content is loading, e.g. put a gif here, or leave empty -->
</builder-component>
<script async src="https://cdn.builder.io/js/webcomponents"></script>
Following is what you get when you do “Get Code” in builder editor, no mention of “model”.
Our preview url is /builder which is currently working for “page” we would like to be able to use same endpoint for additional models
<!-- The script only needs to be included once per page -->
<script async src="https://cdn.builder.io/js/webcomponents"></script>
<!-- Put this component where you want this Builder content to display -->
<builder-component
name="zyus-bottom-nav-blocks"
entry="735323fd39544c12b1a2dea163a34dfb"
api-key="79a2beca42894ade92dce05f54bd8f79">
<!-- Whatever you include inside the tag displays while the content is loading -->
<div style="display: flex; flex-direction: column; align-items: stretch">
<img
style="margin: 10px auto; width: 30px; height: 30px"
