How to enable logging of exceptions

[lewimuchiri]

Certain Exceptions occuring during DataFetching are not logged to the console. i.e. their stack-trace. For example, I have the following code:

@GraphQLApi
public class Test {
    @GraphQLMutation(name = "createTerritories")
    public FastTable<ResponseDto> createTerritories(@GraphQLArgument(name = "territories") FastTable<@Valid CreateTerritoryDto> territories) {
        return territoryService.create(territories);
    }
}

@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
public class CreateTerritoryDto{
    @NotNull
    private AppUser territoryHead;
    ...
}

@Getter
@Setter
@AllArgsConstructor
public class AppUser {
    private String login;
    private String name;
    private String phoneNumber;
}

And I was sending this mutation:

mutation {
  createTerritories(
    territories: [{
      territoryHead: {
        login: "1231rdq3re1d2c",
        name: "User",
        phoneNumber: "12345678"
      },
    ...
    }]
  ) {
    status
}

Upon sending that mutation, no exception log is printed on the console but the GraphQL response is:

Value: [{territoryHead={login=1231rdq3re1d2c, name=User, phoneNumber=12345678}, counterNumber=1, ...}] could not be parsed into an instance of javolution.util.FastTable<CreateTerritoryDto>

Upon further investigation, I discovered that the issue was because the AppUser class did not have a default or no-argument constructor. This took a bit of time to discover and it was very easy to fix (by just adding @NoArgsConstructor lombok anotation on that class). It would have been easier to troubleshoot if the exception stack-trace was being printed on the console.
How can I enable printing of such data fetching exceptions?

I've tried this but it doesn't help:

logging:
  level:
    io.leangen: debug
