nexus-plugin-prisma: Property 'crud' does not exist on type 'ObjectDefinitionBlock<"Query">'

Hi Prisma Team, love the product and trying to work through some Proof-of-Concepts. I hope this isn’t a stupid question, but I can’t seem to generate t.crud using prisma2 generate.

I’m following this guide on Database Access with Prisma 2, but I hit the following error message:

Using ts-node version 8.3.0, typescript version 3.5.2
[ERROR] 12:47:51 ⨯ Unable to compile TypeScript:
src/index.ts:16:7 - error TS2339: Property 'crud' does not exist on type 'ObjectDefinitionBlock<"Query">'.

16     t.crud.findOneFoo();

Both Photon and Nexus appear to have generated successfully after prisma2 generate, but crud is simply not available on the generated Nexus type/library.

The minimal example of my code is as below. Would really appreciate any insight into whats going on with this.

Thanks in advance!
