App reviews, troubleshooting, and recommendations
I'm trying to build the UI for a product discount extension and store the configuration in a metafield associated with the discount. Whenever I run the mutation
mutation MutateMetafield($discId: ID!, $mfId: ID!, $mfValue: String) { discountAutomaticAppUpdate( id: $discId automaticAppDiscount: {metafields: [{id: $mfId, value: $mfValue}]} ) { userErrors { field message } } }
I get the error "The discount doesn't exist", but it works if I run the exact same mutation in the GraphiQL App on the store it works. I've double-checked I've already got the write_discounts scope added to the shopify.app.toml file and I'm using the official JS client to run the mutation. Where else should I check next? Thanks in advance for any help!
Hi Andy_Hanson-Dvo,
Try printing ID in console and make sure correct ID is being sent to graph QL
If it gets resolved then please mark it as a solution.
Good luck
I figured it out. The discount needed to be written by the custom app originally rather than via the GraphiQL app.
Once I deleted the original discount and recreated it through my app I was able to mutate the metafield as expected.
Awesome. Thanks for the update
