I’m trying to use a variable in my input query for a shipping customisation function. I’ve followed the steps here https://shopify.dev/docs/apps/functions/input-output/variables-queries But I’m getting the following error Validation errors • input.variables: Variable definitions are missing. Ens…

Ok the problem was that (differently from what the documentation says) the right syntax is this: [extensions.input.variables] namespace = "$app:my-delivery-function" key = "shipping-config"

Thanks for posting the solution – we indeed have a doc update in the works for this.

I am also doing the same thing but after writing this [extensions.input.variables] namespace = “payment-customization” key = “function-configuration” metafield giving Null, I am stucked to solve this issue.

Are you using the $app prefix? Try to not use that and see if it works.

No, I am not using $app (reserved prefix) for this. [Screenshot from 2023-11-02 14-30-15.png] [Screenshot from 2023-11-02 14-30-07.png]

When you say ‘metafield giving null’, are you getting the “Variable Definitions Are Missing” error, or is the metafield coming back null in your input query? These are two different but related uses of metafields in Functions. https://shopify.dev/docs/apps/functions/input-output/queries-metafields …

Yes, in input query it’s giving null. Getting this response [Screenshot from 2023-11-02 18-11-33.png]
