I am trying to develop my first app and tried to create a metafield following the example linked here.
This is for an app made using $ shopify app create node.
I am new to using graphQL as well. The following error occurred:
GraphQL error: MetafieldDefinitionInput isn't a defined input type (on $definition)
GraphQL error: Field 'metafieldDefinitionCreate' doesn't exist on type 'Mutation'
GraphQL error: Variable $definition is declared by metafieldDefinitionCreate but not used
