      Failure: https://evergreen.mongodb.com/task_log_raw/mongo_node_driver_next_lint_run_typescript_next_6cae4b4f9b37ca760377b3ef08421d12d88d4617_22_06_02_21_30_52/0?type=T#L167

       Sample of errors:

      src/admin.ts(82,41): error TS2322: Type 'Callback<Document> | (CommandOperationOptions & Function)' is not assignable to type 'Callback<Document> | undefined'.
src/admin.ts(106,41): error TS2322: Type 'Callback<Document> | (CommandOperationOptions & Function)' is not assignable to type 'Callback<Document> | undefined'.
src/admin.ts(125,41): error TS2322: Type 'Callback<Document> | (CommandOperationOptions & Function)' is not assignable to type 'Callback<Document> | undefined'.

       
      Typescript's next version appears to add an intersection with Function instead of narrowing our function argument overloading to Callback when we use typeof x === 'function'.

      Update: This ticket was filed when TS 4.8 was in beta, this issue was resolved before the official release.
