[Admin API] - updateCustomer - Error

[matigastirami]

There is an error when you try to update a customer. I'll let the request and response example below:
mutation { updateCustomer( input: { firstName: "test" lastName: "test" phoneNumber: "1234567890" emailAddress: "[email protected]" id: "134", title: "sr" } ){ ... on Customer{ id }, ... on ErrorResult{ errorCode, message } } }

Response:
{"errors":[{"message":"i.hasOwnProperty is not a function","locations":[{"line":3,"column":17}],"path":["updateCustomer"]}],"data":null}

Thanks for the report, I can reproduce this.

Tracked it down to the fact that the graphql-js lib creates input arg objects with null prototypes (see graphql/graphql-js#504). The fix is to replace this line:

vendure/packages/core/src/service/services/customer.service.ts

Line 242 in adaa50d

i.hasOwnProperty('emailAddress');

with

Object.hasOwnProperty.call(i, 'emailAddress');

Will fix for the next release.
