Hi, I neet to build an app for fulfillment services, I am trying to create a fulfillment service with this mutation
mutation fulfillmentServiceCreate($name: String!, $callbackUrl: URL!) {
fulfillmentServiceCreate(name: $name, callbackUrl: $callbackUrl) {
fulfillmentService {
id
serviceName
callbackUrl
location {
id
}
}
userErrors {
field
message
}
}
}
and I have an issue because the response came empty
{FulfillmentService:{Id: Location:{Id:}} UserErrors:}
I made sure that mi callbackUrl is right and returns 200, the accessToken is right and the name of my shop
but I am still getting an emptyResponse, When I go to admin panel of shopify I can see my fulfilmentServices created before
I need ypur help please.
