Typescript redux saga-调用具有调用效果的api时发生编译错误

我试图调用模拟API，但出现以下错误： 错误TS2345:类型为“Promise”的参数不能分配给类型为“CallEffectNamedFn”的参数。 类型“Promise”不能分配给类型“{context:{[x:string]：Func0；}；fn:string；}”。 类型“Promise”中缺少属性“context”

redux saga的版本为：^0.16.0 tsConfig： 目标：es6， lib:[es6，dom]

这里是模拟API：

    getAllMembersAsync() : Promise<Program[]> {
    const promise : Promise<Array<Program>> = new Promise((resolve, reject) 
=> {
            var members : Array<Program>;

            members = ProgramsData.map((currentProgram) => {
                var program : Program = new Program();

                program.code = currentProgram.code;
                program.nom = currentProgram.nom;
                program.cours = currentProgram.cours;

                return program;
            });

            resolve(members);
        // });
    });
    return promise;
}

这是我的传奇：

import {call, put, takeLatest} from 'redux-saga/effects';
import { receivedPrograms, FetchPrograms, FETCH_PROGRAMS } from 
'../actions/programActions';
import { Program } from '../model/program';
import programAPI from '../api/programAPI';

function* fetchPrograms(action: FetchPrograms) {
 let programs: Array<Program>;
 programs = yield call(programAPI.getAllMembersAsync());
 yield put(receivedPrograms(programs));
}

有人能告诉我我做得不对吗

谢谢大家

这是一个打字错误。。。这里是解决办法

programs = yield call(programAPI.getAllMembersAsync);
