在我们的后端服务器上添加 elastic-apm-node 后，我们每天会收到数百次以下错误。谁能建议可能导致这种情况的原因？

我们看到的错误是这样的：

     { SyntaxError: Unexpected token " in JSON at position 0
    at JSON.parse (<anonymous>)
    at createStrictSyntaxError (/usr/src/app/node_modules/body-parser/lib/types/json.js:158:10)

  type: 'entity.parse.failed',
  traceId: 'ERR-344BC630',
  [Symbol(ElasticAPMErrorReported)]: true }

我认为我们运行 node v10.x 但我不确定。

该服务是建立在feathersJS 之上的，而feathersJS 又是建立在Express 之上的。

我们像这样启动 APM：

require("elastic-apm-node").start({
    serviceName: "serviceX",
    serverUrl: "http://xxx:8200"
});
