Describe the bug

The following code should fail type checking but does not:

interface SomeBody {
  field1: string;
  field2: string;
}
async function fetchSomething(): Promise<SomeBody > {
  // Buggy code is missing a call to .data on the AxiosResponse
  return await axios.get('http://example.com/some/api'); // TypeScript is fine, but it should not be
}

If you introduce an intermediate variable typechecking does fail:

async function fetchSomething(): Promise< SomeBody > {
  const response = await axios.get('http://example.com/some/api');
  return response; // TS2322: Type  AxiosResponse<any, any>  is not assignable to type SomeBody
}

Expected behavior

The following code fails type checking as it does when an intermediate variable is introduced:

interface SomeBody {
  field1: string;
  field2: string;
}
async function fetchSomething(): Promise<SomeBody > {
  // Buggy code is missing a call to .data on the AxiosResponse
  return await axios.get('http://example.com/some/api'); // TypeScript is fine, but it should not be
}

See microsoft/TypeScript#56532 for a possible fix to the typings.
