Avoid checking for TRPCClientError, and return the error in client query/mutate

export const customLink: TRPCLink<AppRouter> = () => {
  return ({ next, op }) => {
    return observable((observer) => {
      const unsubscribe = next(op).subscribe({
        next(value) {
          observer.next(value);
        },
        error(err) {
          if (err instanceof TRPCClientError) {
            const errorResponse: OperationResultEnvelope<unknown> = {
              result: {
                type: "data",
                data: {
                  zodError: JSON.parse(err.message)[0].message,
                },
              }
            };
            observer.next(errorResponse);
          } else {
            observer.error(err);
          }

        },
        complete() {
          observer.complete();
        },
      });
      return unsubscribe;
    });
  };
};

    const login = async(e:any) =>{
        e.preventDefault();
        cargando=true;error=null;
        await tick();
            let res = await trpc.cuentas.login.query(loginData) 
            cargando=false
            
            if ('zodError' in res) return error = String(res.zodError)
            
            if (!res.token) return error = res.error

            usuarioJWT.set(res.token)
    }
