In the Miva json api there is this function ProductVariantList_Load_Product (https://docs.miva.com/json-api/funct...t_load_product)

which returns all the variants of a product including the combinations of attributes each variant is associated with (dimensions object)

I’m trying to use this function inside Miva templates but seems like the mvt version of the same function (https://docs.miva.com/code-samples/l...-for-a-product) doesn’t include the combinations of attributes.

Because of that I have to loop then through all the variants and pull the attributes by separate calls.
Code:
<mvt:do file="g.Module_Library_DB" name="l.success" value="ProductVariantList_Load_Product( l.settings:product:id, l.settings:variants )" />
<mvt:foreach iterator="variant" array="variants">
<mvt:do file="g.Module_Library_DB" name="l.success" value="ProductVariantList_Load_Variant( l.settings:product:id, l.settings:variant:variant_id, l.settings:variant:attributes )" />

 </mvt:foreach>
Now this is causing troubles as we have products with hundreds of variants and the server response time (TTFB) for those is up to 40 seconds.

I figured out that it is caused exactly by multiple calls of ProductVariantList_Load_Variant inside the foreach loop.

So the question is how I do pull all variants of a product including the combinations of attributes each variant is associated with by a single function call from inside a Miva template?
