TypeError error e is not a function and TypeError error Function expected

[mathieux51]

Hi @rauchg and @leo,

I recently added async-retry to the project I'm working on because I was getting a lot of ChunkLoadError Loading chunk 6 failed in Sentry. This is how I currently use it:

import loadable from '@loadable/component'
import retry from 'async-retry'

const Dashboard = loadable(() =>
  retry(() => import(/* webpackChunkName: "Dashboard" */ 'containers/pages/Dashboard'), {
    factor: 1,
    maxTimeout: 10000,
  })
)

I'm now getting a new error on Sentry from async-retry package. I'm not sure to understand it:

function runAttempt(num) {
  32       var val;
  33
  34       try {
  35         val = fn(bail, num);
  36       } catch (err) {
  37         onError(err, num);
  38         return;
  39       }
  40
  41       Promise.resolve(val)
  42         .then(resolve)
  43         .catch(function catchIt(err) {
  44           onError(err, num);
  45         });
  46     }

According to Sentry the problem is on line 35 of this function. I get 3 different error messages:

• TypeError error e is not a function
• TypeError error Function expected
• TypeError e is not a function. (In 'e(c,t)', 'e' is an instance of Promise)

Am I doing something wrong or is it a bug?
I would be happy to help either way.
