Nootification not sent from AWS lambdas

I’m using serverless framework to deploy lamdbas containing bugsnag.

I’m using aws-serverless-express to have express running.

I had to write my own middleware to ensure the bugsnag request is fulfilled before finishing the lambda

From this file https://github.com/bugsnag/bugsnag-js/blob/next/packages/plugin-express/src/express.js#L49

I replaced this

const errorHandler = (err, req, res, next) => {
  if (req.bugsnag) {
    req.bugsnag.notify(createReportFromErr(err, handledState))
  } else {
    client._logger.warn(
      'req.bugsnag is not defined. Make sure the @bugsnag/plugin-express requestHandler middleware is added first.'
    )
    client.notify(createReportFromErr(err, handledState, getRequestAndMetaDataFromReq(req)))
  }
  next(err)
}

by

app.use(async (err, req, res, next) => {
  await new Promise(resolve => {
    req.bugsnag.notify(createReportFromErr(err, handledState), {}, resolve)
  })
  next(err)
})

that way it ensures the request has been fulfilled.

Could this become an option?

Can we have an official solution for this? More than a year with no actual solution

The new AWS Extensions API might offer good ways to solve this issue: https://docs.aws.amazon.com/lambda/latest/dg/runtimes-extensions-api.html
