Issue for Demo Page

[philipp-reich]

Hello guys,

first of all: GREAT JOB! 🎉 i love it so much 👍

i found an issue on the Demo Angular Storefront. when i selected a single product and continue to the "payment" view i got an error for "setShippingMethod"

{
  "operationName":"SetShippingMethod",
  "variables":{
    "id":"1"
  },
  "query":
    "mutation SetShippingMethod($id: ID!) {
        setOrderShippingMethod(shippingMethodId: $id) {
          ...Cart
        ...ErrorResult
        __typename
      }
    }

    fragment Cart on Order {
        ...    
    }

    fragment ErrorResult on ErrorResult {
        errorCode
      message
      __typename
    }"
}

Response message:

{
    "errors": [
        {
            "message": "Variable \"$id\" of type \"ID!\" used in position expecting type \"[ID!]!\".",
            "locations": [
                {
                    "line": 1,
                    "column": 28
                },
                {
                    "line": 2,
                    "column": 44
                }
            ]
        }
    ]
}

i had the same issue when i clone the repo and using the vendure 2.0.

my solution was to change the GraphQL mutation to:

export const SET_SHIPPING_METHOD = gql`
  mutation SetShippingMethod($id: [ID!]!) {
    setOrderShippingMethod(shippingMethodId: $id) {
      ...Cart
      ...ErrorResult
    }
  }
  ${CART_FRAGMENT}
  ${ERROR_RESULT_FRAGMENT}
`;

before: mutation SetShippingMethod($id: ID!) {
after: mutation SetShippingMethod($id: [ID!]!) {

Maybe it helps...

Hi, thanks for the report!
I'm a bit confused because that mutation did get updated: https://github.com/vendure-ecommerce/storefront-angular-starter/blob/master/src/app/checkout/components/checkout-shipping/checkout-shipping.graphql.ts#L55

but I just tested on the live demo and I get the same error, which makes me think the demo instance hasn't been updated.

But do you also get the error when you clone this repo locally?

[philipp-reich]

Hey,
no. the local clone looks good. But tbh i checked only the repo on github. i updated my storefront from version 1 to 2. i didnt test it 🙈

Thanks for the info! So I now updated the live demo, and it works now, so I'll close this issue.
