Cannot read property 'getFields' of undefined about gql-generator HOT 2 CLOSED

@Hasan-git Can you provide a schema which can reproduce this error? I think its todo with the schema

from gql-generator.

schema {
query: Query
mutation: TenantMutation
}
......
......

type TenantMutation {
createLocation(location: LocationInput!): Location
createLookup(lookup: LookupInput!): Lookup
createLookups(lookups: [LookupInput]!): [Lookup]
}

the problem is going over there ^^^^, whenever I delete mutation it works, and queries will be created successfully !!

when I change "TenantMutation" to "mutation" it works too

from gql-generator.
