Answer 1

I ran into the same issue. This is most likely caused by the fact that the .graphql files are ignored in build time and not copied to /dist. Interestingly, I didn't have that before and the build seemed to complete just fine, it appeared only today.

I found a workaround to the problem proposed by the NestJS creator: https://github.com/nestjs/graphql/issues/135

Answer 2

https://docs.nestjs.com/cli/monorepo#assets

There is assets option in nestjs. This is the right way to do it in nestjs.
