Issue facing while using Shopify function for Product Discount

[yedla_dinesh]

Facing an issue with product discounts using the 'discountAutomaticAppCreate' mutation. When dealing with a large volume of JSON data within metafields, the discounts don't seem to apply.

For example: 

const discount = {
    functionId,
    combinesWith: form.combinesWith,
    startsAt: form.startDate,
    endsAt: form.endDate,
    metafields: [
        {
            namespace: metafields.config.namespace,
            key: metafields.config.key,
            type: "json",
            value: JSON.stringify({
                quantity: parseInt(form.config.quantity),
                percentage: parseFloat(form.config.percentage)
            })
        }
    ]
};

Suppose I have a large volume of data stored within a single metafield in that case the discount isn't applying. However, when I removed some data from the metafield, the discount applied perfectly. Has anyone else experienced a similar problem, or might there be something crucial that I might have overlooked in this context?


Any suggestions on how to resolve this,  @Liam @Nick_Wesselman

Hey @yedla_dinesh 

Checking on this.

I've reviewed the Shopify documentation, and it appears that there are limitations regarding Metafields values.

Here's the link for reference: https://shopify.dev/docs/apps/functions/input-output#limitations

Has anyone else encountered a similar issue? How have you tackled this kind of problem?

Hey @yedla_dinesh 

Thanks for your patience.

You're spot on. Team said:

> They are likely hitting the 10KB metafield value limit, and their discount isn’t applying because the metafield value appears null in that case.

Asking for workarounds and will report back.
