Unable to activate Cart Transform Function

[BrandoCommando]

Hello there! Is there something special that needs to be done to activate Cart Transformation functions? I've tried the stock/template Bundling function based on Rust, and I've tried my own version (with JS compiled into Wasm), but I cannot see any evidence that the function is even being run!

I brought this question up on the recent Checkout Extension Q&A sessions, but the only answer I got was that "Bundling is not available to the general public yet"! I am quite aware of the fact that a Partner account is necessary, and development requires a partner development store. I have met those requirements.

I ask if there's something special that must be done because Cart/Checkout validation functions need to be whitelisted, but I haven't found anywhere in the store admin section to whitelist/activate my cart transformation functions. Then, when I check the extension "runs", it is always empty, no matter what I do in the store checkout. All the other function types I have been able to get to work, but the bundling function still eludes me.

Please advise, and thanks for your time.

I am having the same problem as well. The sample app works just fine but when I try to rebuild the function on my own, it isn't working and giving me a ton of errors when I attempt to deploy said extension. Did you try to do npm run deploy to make this extension live with your app?

I've figured it out! You need to run the following mutation to register the extension:

mutation cartTransformCreate($functionId: String!) {
  cartTransformCreate(functionId: $functionId) {
    cartTransform {
      functionId
      id
    }
    userErrors {
      field
      message
    }
  }
}

@BrandoCommando can you share your wasm? I can’t get my app to even compile after doing the standard extensions from Shopify…

My npm run deploy throws tons of errors around rust and how something about how everything must be true

Hi! For others reading this issue, please look at the customized Bundles guide. We added a section that describes how to register the function in a shop.

Thanks for getting that updated! Seems like something that should be configurable though, like cart validators.
