It seems I am experiencing the same problem when dealing with any mutation using GraphQL. Here the example of the code:
`mutation productCreate {
productCreate(input: {title: "title"}) {
product {
id
}
}
}
`
example of the response:
`{
"errors": [
{
"message": "Field 'productCreate' doesn't exist on type 'Mutation'",
"locations": [
{
"line": 2,
"column": 3
}
],
"path": [
"mutation productCreate",
"productCreate"
],
"extensions": {
"code": "undefinedField",
"typeName": "Mutation",
"fieldName": "productCreate"
}
}
]
}`
It seems like there is some issue with the Shopify API and it doesn`t allow me to do any mutation.
