Missing ClientInterfaceName in GenerateConfig?

[hyrefeldt-ourstudio]

I get this error which looks like an error caused by some missing config

panic: runtime error: invalid memory address or nil pointer dereference

I'm using go1.18 so I have installed the executable gqlgenc via go install github.com/Yamashou/gqlgenc since go get doesn't install executables in go1.18. Prior to that I did run go get -u github.com/Yamashou/gqlgenc. The .gqlgenc.yml that i use looks like

model:
  package: backend
  filename: ./internal/backend/graphql-service_gen.go # https://github.com/99designs/gqlgen/tree/master/plugin/modelgen
client:
  package: backend
  filename: ./internal/backend/graphql-service.go # Where should any generated client go?
query:
  - "./internal/backend/graphql/graphql-service/query/*.graphql" # Where are all the query files located?
endpoint:
  url: <the url to the graphql api endpoint that I want to generate from>

What happens that the models in graphql-service_gen.go does seem to be generated correctly. And I have not done any changes to the queries in ./internal/backend/graphql/graphql-service/query so I don't expect any changes in ./internal/backend/graphql-service.go. But since I get the error above I want to double check that I'm not missing some important config.

I have the same issue but you were on the right track spoting its root cause!

Seems @Yamashou fixed it in clientgenv2 (Yamashou/gqlgenc@7c74e5d7739df1e579d80261f30e928cdb242a3c) but not in clientgen.

The following patch fixes it for clientgen:

Do you have to use v1 clients? If so, I will try to correct v1 as well as v2
