弹性APM：与Apollo / graphQL一起使用时，猫鼬范围无法找到交易

问题描述

我正在使用Elastic APM。我发现当以某种方式与GraphQL / Apollo Server一起使用时，猫鼬集成无法正常工作。我写了一个这样的apollo-server插件来启动/停止事务：

import apm from 'elastic-apm-node/start';
import _ from 'lodash';
import { gql } from 'apollo-server-express';

const apmPlugin = {
  requestDidStart: (requestContext) => {
    const query = gql`${requestContext.request.query}`;
    const type = _.get(query,'deFinitions[0].operation','');
    const funcName = _.get(query,'deFinitions[0].name.value','');
    const txnName = type && funcName ? `${type} ${funcName}` : '/gql';
    const txn = apm.startTransaction(txnName,'graphql');
    return {
      didEncounterErrors: (err) => {
        if (txn) {
          txn.result = err.errors.length === 1 ? err.errors[0].name : 'error';
        }
      },willSendResponse: (res) => {
        if (Array.isArray(res.response.errors).length === 0) {
          txn.result = 'success';
        }
        if (typeof txn?.end === 'function') txn.end();
      },};
  },};

它有效，但是我缺少猫鼬的跨度，当我启用跟踪时，这是我看到的：

start trace {
  trans: 'ddc03cb86cf71448',parent: undefined,trace: '7127e63abe8e6d5086d36c13deee8183',name: 'unnamed',type: 'graphql',subtype: null,action: null
}
start span {
  span: '94fc2307e19dd187',parent: 'ddc03cb86cf71448',name: 'GraphQL: UnkNown Query',type: 'db',subtype: 'graphql',action: 'execute'
}
intercepted call to graphql.execute { id: 'ddc03cb86cf71448' }
Mongoose: yyy.findOne({ domainSlug: 'xxx' },{ projection: {} })
no active transaction found - cannot build new span
Mongoose: yyy.findOne({ email: 'xxx',company: ObjectId("5f1ab19010469e8eb952e754") }},{ projection: {} })
no active transaction found - cannot build new span
Mongoose: roles.find({ _id: { '$in': [ ObjectId("5f1ab19010469e8eb952e786") ] } },{ skip: undefined,limit: undefined,perDocumentLimit: undefined,projection: {}})
no active transaction found - cannot build new span
ended span {
  span: '94fc2307e19dd187',name: 'GraphQL: xxx',action: 'execute'
}
encoding span {
  span: '94fc2307e19dd187',type: 'db'
}
sending span {
  span: '94fc2307e19dd187',type: 'db'
}
sending transaction {
  trans: 'ddc03cb86cf71448',trace: '7127e63abe8e6d5086d36c13deee8183'
}
ended transaction {
  trans: 'ddc03cb86cf71448',result: 'success',name: 'mutation doLogin'
}

请注意，在那些猫鼬调用之前和之后创建的跨度都很好，但是猫鼬调用似乎无法以某种方式找到活动交易。

no active transaction found - cannot build new span
