Weaviate javascript client“.withAsk”返回“undefined”,我缺少什么?

我已经按照 quick start manual 。

我已经导入了数据,客户端连接正常。

然后对于 ask 函数,我实现了以下内容:

export async function question(collection: Collections, question: string) {
  await client.graphql
    .get()
    .withClassName(collection)
    .withAsk({ question })
    .withFields('memberName _additional { answer { hasAnswer property result startPosition endPosition } }')
    .withLimit(5)
    .do()
}

question(Collections.TeamMember, 'Who has painting as a hobby?')
  .then((result) => { console.log(result) });

这将返回 undefined .我本以为它会回来 Sarah Mitchell 。

其他信息:

架构

我手动创建了一个架构,以便 qna-openai 可以添加到 moduleConfig 像 described here :

export async function addClassToSchema(classObject: object) {
  const res = await client.schema.classCreator().withClass(classObject).do();
}

类对象:

{
  "class": "TeamMember",
  "vectorizer": "text2vec-openai",
  "moduleConfig": {
    "text2vec-openai": {},
    "qna-openai": {
      "model": "text-davinci-002",
      "maxTokens": 16,
      "temperature": 0.0,
      "topP": 1,
      "frequencyPenalty": 0.0,
      "presencePenalty": 0.0
    }
  },
  "properties": [
    {
      "name": "teamName",
      "dataType": ["text"]
    },
    {
      "name": "memberName",
      "dataType": ["text"]
    },
    {
      "name": "jobDescription",
      "dataType": ["text"]
    },
    {
      "name": "responsibilities",
      "dataType": ["text"]
    },
    {
      "name": "education",
      "dataType": ["text"]
    },
    {
      "name": "hobbies",
      "dataType": ["text"]
    }
  ]
}

当我得到 https://test-cluster-name.weaviate.network/v1/schema 我得到以下回复:

对象

然后将成员列表导入Weaviate实例。

export async function teamMembersImport() {
  let batcher = client.batch.objectsBatcher();

  // When importing the teamsJson, or when the teamsJson becomes large,
  // implement batching system as per example on https://weaviate.io/developers/weaviate/quickstart#step-5-add-objects
  for (const team of teamsJson) {

    const memberObjects = team.members.map((teamMember) => ({
      class: 'TeamMember',
      properties: {
        teamName: team.teamName,
        memberName: teamMember.memberName,
        jobDescription: teamMember.jobDescription,
        responsibilities: teamMember.responsibilities,
        education: teamMember.education,
        hobbies: teamMember.hobbies,
      }
    }));

    batcher.withObjects(...memberObjects);
  }

  await batcher.do().then((batchResponse) => {
    batchResponse.map((weaviateObjectsGet) => {

      if (weaviateObjectsGet.result.status === 'FAILED') {
        console.log(weaviateObjectsGet.result.errors);
        return;
      }

      if (weaviateObjectsGet.result.status === 'SUCCESS') {
        console.log(`added teamMember ${weaviateObjectsGet.properties.memberName} to ${weaviateObjectsGet.class}`)
      }
    });
  });
}

A GET https://test-cluster-name.weaviate.network/v1/objects 将产生以下响应:
