New Build Errors

[JamieBradders]

Received a couple of emails from readers regarding build errors they are experiencing when completing the tutorial. Latest instance is shown below:

Jamie,
I moved ahead slightly, am getting following error when building your project.
Checked some other graphQL queries, which work perfectly fine otherwise, using POSTMAN or Shopify’s GraphQL tool.

If, possible, could you please advise

Apparently this query works through an API client such as Postman, so it has to be related to the code. The emails started arriving not long after Shopify Unite so I'm not sure if there's been a breaking change in the latest version of the Storefront API that needs addressing.
