cannot "delete all failed jobs"

[bradwbradw]

repro: in Failed screen, click the gear icon dropdown, then click "delete all failed jobs"

expected: the jobs disappear

actual: the jobs are still there. I can see in the browser console there is an error:

Uncaught TypeError: Cannot read property 'name' of undefined
    at Object.deleteByStatus (RedisHandler.js:35)
    at HTMLAnchorElement.onclick (VM1131 failed:1)
deleteByStatus @ RedisHandler.js:35
onclick @ VM1131 failed:1

using versions:

    "bull": "2.2.6",
    "bull-ui": "1.2.1",

here is one of the failed jobs i have:

Job ID: 4
Type: test job
Status: failed

Data: {
  "num": 39906
}
