How to set the Apollo GraphQL server to accept an object as a variable to a mutation? - graphql

Question

Currently, I'm trying to pass an object as a variable to a mutation as shown below:
type ShopLocation {
lane1: String
lane2: String
city: String
postalCode: String
country: String
}
type ShopResponse {
statusCode: Int
messageCode: String
data: String
}
type Mutation {
createShop(
name: String
email: String
location: ShopLocation
): ShopResponse
}
But I get the following error:
{
"error": {
"errors": [
{
"message": "The type of Mutation.createShop(location:) must be Input Type but got: ShopLocation.",
"extensions": {
"code": "GRAPHQL_VALIDATION_FAILED",
"exception": {
"stacktrace": [
"Error: The type of Mutation.createShop(location:) must be Input Type but got: ShopLocation.",
" at assertValidSchema (.../node_modules/graphql/type/validate.js:71:11)",
" at Object.validate (.../node_modules/graphql/validation/validate.js:55:35)",
" at Promise.resolve.then (.../node_modules/apollo-server-core/src/runQuery.ts:188:30)",
" at <anonymous>",
" at process._tickDomainCallback (internal/process/next_tick.js:228:7)"
]
}
}
}
]
}
}
Any idea how to properly do this?

You need to make the ShopLocation with input keyword instead of type,
input ShopLocationInput {
lane1: String
lane2: String
city: String
postalCode: String
country: String
}
type ShopResponse {
statusCode: Int
messageCode: String
data: String
}
type Mutation {
createShop(
name: String
email: String
location: ShopLocationInput
): ShopResponse
}
