As in title. Try to use graphQl API using this mutation [https://help.shopify.com/en/api/graphql-admin-api/reference/mutation/ordereditaddvariant this error is thrown ](https://help.shopify.com/en/api/graphql-admin-api/reference/mutation/ordereditaddvariant)Error: Field 'orderEditAddVariant' doesn't exist on type 'Mutation' seems that something is missing.

Can you share the exact GraphQL query you are sending the to graphql endpoint, and also the endpoint’s URL.

Anything related to order editing. Im even unable to start order editing by orderEditingBegin mutation. Error is the same

mutation orderEditBegin{ orderEditBegin(id: some_order_id) { calculatedOrder { id } userErrors { field message } } };

throws Field ‘orderEditBegin’ doesn’t exist on type ‘Mutation’

Im using the shopify-api-node npm package so i dont care what is the url by myself. But i see that url is proper http://greg-test-5.myshopify.com/admin/api/graphql.json so it is not fault of library i use.

Hey greg12!

Can you try specifying an API version in that URL?

If you don’t specify a version, you’ll be served the oldest currently supported version, which is 2019-04.

Toggling through the version selector at the top of the orderEditBegin mutation docs, I can see that this mutation doesn’t exist in the schema until 2020-01.

Can you swap your URL to http://greg-test-5.myshopify.com/admin/api/2020-01/graphql.json
