Functional resolver with two injected services (Angular 15)

In my resolver, I am trying to inject two services, which uses response of one as input for next service call:

export const addressResolver : ResolveFn<Address> = (
  route: ActivatedRouteSnapshot
) => {

  return inject(UserService).getUserInfo().pipe(
    mergeMap((user: any) => {
      return inject(AddressService).getAddressByUserId(route.params['addressType'], user.id).pipe(
        map((res:any)=>{
           return res;
        }
      ));
    })
  );
};

This code throwing error as

Uncaught (in promise): Error: NG0203: inject() must be called from an injection context such as a constructor, a factory function, a field initializer, or a function used with EnvironmentInjector#runInContext

Can anyone please help what is missing here in this code block. Thanks in advance

Could you try assigning them to variables and then performing the calls?

export const addressResolver : ResolveFn<Address> = (
  route: ActivatedRouteSnapshot
) => {
  const userServiceInjector = inject(UserService);
  const addressServiceInjector = inject(AddressService);
  return userServiceInjector.getUserInfo().pipe(
    mergeMap((user: any) => {
      return addressServiceInjector.getAddressByUserId(route.params['addressType'], user.id).pipe(
        map((res:any)=>{
           return res;
        }
      ));
    })
  );
};
