Bug description
I used CognitoIdentityServiceProvider.adminListUserAuthEvents for getting user auth events but received an invalid result. I logged in from Opera but Cognito displays that I used Chrome 8 (this is a mistake).

I could fix that if I get original navigator.userAgent (for example: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36 OPR/72.0.3815.400), but I only received data like that:

 {
    "EventId": {EVENT_ID},
    "EventType": "SignIn",
    "CreationDate": {CREATION_DATE},
    "EventResponse": "Pass",
    "EventRisk": {
      "RiskDecision": "AccountTakeover",
      "RiskLevel": "Low",
      "CompromisedCredentialsDetected": false
    },
    "ChallengeResponses": [
      {
        "ChallengeName": "Password",
        "ChallengeResponse": "Success"
      }
    ],
    "EventContextData": {
      "IpAddress": {MY_IP_ADDR},
      "DeviceName": "Chrome 8, Linux",
      "City": {MY_CITY},
      "Country": {MY_COUNTRY}
    }
  }

I wouldn't like to make the crutch, to clarify this information, like creating preauth Cognito trigger which will log this information in another Table and handle this flow by myself.

Crutch for detection browser I found here

Is the issue in the browser/Node.js?
I got this data from CognitoIdentityServiceProvider.adminListUserAuthEvents in my Lambda function

If on Node.js, are you running this on AWS Lambda?

Yes

Details of the browser/Node.js version
local sh:

node -v
v12.16.1

serverless config:

...
runtime: nodejs12.x
...

SDK version number

dependencies:

yarn list v1.22.10

To Reproduce (observed behavior)

• create a login from Opera like testUser
• get adminListUserAuthEvents of its user
• you can see in the result, that instead of Opera Chrome is displayed

Expected behavior
I expect to get a valid name of the browser which the user uses for login, or getting the original userAgent field

Screenshots
none

Opera is based on Chromium, this could be why.

@uncodable

Opera is based on Chromium, this could be why.

I know that, but there are some hacks on how to avoid this mistake

For example, my userAgent from Opera on Ubuntu:
Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36 OPR/72.0.3815.400

So, this string includes OPR/72.0.3815.400 for detecting that this is the Opera.

So, what I want?:
I want to get the correct name of the browser.

For example, I see some ways to solve this problem:

• AWS will add original userAgent field to the answer from CognitoIdentityServiceProvider.adminListUserAuthEvents
  
  
  
  • AWS will update his method of browser detecting

Thanks for opening this issue, this does seem to be a Cognito issue and not SDK, let me forward a request to them, will update the issue once I have a response from the team.

Soft update: The Cognito team has acknowledged the issue, they are working on the fix, while there is not a fixed ETA on it, it should be in January.
