Teams Backend stopped working

[golubenkoff]

Expected Behavior

Connected to Teams and Members Loaded

Current Behavior

Message":"Error authenticating to Teams"
Data":{"CommandName":"Invoke-RestMethod"
Message":"The remote server returned an error: (404) Not Found."
RequestUri":"https://webchat.botframework.com/v3/conversations/19:262ca4f4ea7a9f172c5ee99d4aa@thread.tacv2/members/"

Possible Solution

I think it is connected with API deprecation - is it possible to somehow quickly fix this?
See url below with possible changes

Steps to Reproduce (for bugs)

Check this:
https://docs.microsoft.com/en-us/microsoftteams/platform/resources/team-chat-member-api-changes
https://docs.microsoft.com/en-us/microsoftteams/platform/bots/how-to/get-teams-context?tabs=json#tabpanel_CeZOj-G++Q_json

I think issue here:
[void]LoadUsers()
Line 9615: $uri = "$($this.ServiceUrl)v3/conversations/$($this.TeamId)/members/"

• here should be new paged users load

Context

Your Environment

• Module version used: ModuleVersion = '0.14.0'
• Operating System and PowerShell version: PowerShell 5.1, Windows Server 2019 Datacenter

Managed to fix this via:
TeamsBackend.ps1

Here:
# Populate the list of users the team
[void]LoadUsers()

Replace this:

$this.LogDebug('Getting Teams users')

$uri = "$($this.ServiceUrl)v3/conversations/$($this.TeamId)/members/"
$headers = @{
    Authorization = "Bearer $($this.Connection._AccessTokenInfo.access_token)"
}
$members = Invoke-RestMethod -Uri $uri -Headers $headers
$this.LogDebug('Finished getting Teams users')

To this:

$this.LogDebug('Getting Teams users')

$uri = "$($this.ServiceUrl)v3/conversations/$($this.TeamId)/pagedmembers?pageSize=500"
$headers = @{
   Authorization = "Bearer $($this.Connection._AccessTokenInfo.access_token)"
}

$members = @()
do {
   $Results = ''
   $StatusCode = ''
   do {
       try {
           $Results = Invoke-RestMethod -Headers $headers -Uri $Uri -UseBasicParsing -Method 'GET' -ContentType 'application/json'

           $StatusCode = $Results.StatusCode
       } catch {
           $StatusCode = $_.Exception.Response.StatusCode.value__

           if ($StatusCode -eq 429) {
               $this.LogDebug('Got throttled by Microsoft. Sleeping for 45 seconds...')
               Start-Sleep -Seconds 45
           } else {
               $this.LogDebug("Error Populating the list of users for the team: $($_.Exception.Message)")
           }
       }
   } while ($StatusCode -eq 429)
   if ($Results.continuationToken) {
       $uri = "$($this.ServiceUrl)v3/conversations/$($this.TeamId)/pagedmembers?pageSize=500&continuationToken=$($Results.continuationToken)"
       $members += $Results.members
   } else {
       $members += $Results.members
   }
} while ($Results.continuationToken)
$this.LogDebug('Finished getting Teams users') 

Checked on my environment - with 8000+ users - all is OK.
