Apollo客户端Graphql查询变量类型错误

Question

I am trying to execute delete query in which IDis required but I am getting an error. "Variable "$id" of required type "ID!" was not provided"

Query

export const DELETE_CUSTOMER = gql`
    mutation deleteCustomer($id:ID!){
        deleteCustomer(
            _id: $id
        )
    }
`

Mutation code in vuex actions

deleteCustomer(vuexContext,id){
        return apollo
        .mutate({
            mutation: DELETE_CUSTOMER,
            variables: id.toString()
        })      
        .then(()=>{
            vuexContext.commit('deleteCustomer',id.toString());
        })
        .catch((err) => {
            throw err;
        });

    }

The variables option should be an Object, with each property mapping to an individual variable referenced inside your query. You cannot assign the value of an individual variable to variables like you're doing. The corrected method call would look something like:

apollo.mutate({
  mutation: DELETE_CUSTOMER,
  variables: { id: id.toString() },
})
