Unable to connect with new PSZoom version

[AstroFish849]

I'm getting the error
ConvertFrom-Json : Cannot bind argument to parameter 'InputObject' because it is null.
At C:\Users\User\Documents\WindowsPowerShell\Modules\PSZoom\2.0.1.0\Public\Utils\New-OAuthToken.ps1:78 char:35
$token = ($response. Content | ConvertFrom-Json).access_token

Connect-PSZoom : Unable to retrieve token for account ID xxxxx.

I'm using the command
Connect-PSZoom -AccountID 'XXXX' -ClientID 'XXXX' -ClientSecret 'XXXX'

These settings are from the new Server-to-Server OAuth app I've created on Zoom.

What am I doing wrong?

The command looks well formatted to me. I tested 2.0.1.0 in PowerShell 5 and 7, and it's working as suspected. I also tried entering wrong credentials and the same error was returned. I suspect it's with how the app was set up or the credentials are not correct.

I've re-created the app and still getting the same error
ConvertFrom-Json : Cannot bind argument to parameter 'InputObject' because it is null.

I would try making the calls using a plain powershell script or even testing your app with Postman. See https://marketplace.zoom.us/docs/guides/guides/postman/using-postman-to-test-zoom-apis/. The script at the bottom of this comment should return the following when succesful:

New-OAuthToken @params
VERBOSE: POST with 0-byte payload
VERBOSE: received -byte response of content type application/json
VERBOSE: Acquired token.
System.Security.SecureString

or error:

New-OAuthToken @params
VERBOSE: POST with 0-byte payload
VERBOSE: received -byte response of content type application/json

Here's the script:

        $AccountID,

        [Parameter(valuefrompipeline = $true, mandatory = $true, HelpMessage = "Enter Zoom App Client ID:", Position = 1)]
        [String]
        $ClientID,

        [Parameter(valuefrompipeline = $true, mandatory = $true, HelpMessage = "Enter Zoom App Client Secret:", Position = 2)]
        [String]
        $ClientSecret

    )

    $uri = "https://zoom.us/oauth/token?grant_type=account_credentials&account_id={0}" -f $AccountID

    #Encoding of the client data
    $IDSecret = $ClientID + ":" + $ClientSecret 
    $EncodedIDSecret = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes($IDSecret))

    $headers = @{
        "Authorization" = "Basic $EncodedIDSecret"  
    }
            
    try {
        $response = Invoke-WebRequest -uri $uri -headers $headers -Method Post -UseBasicParsing
    } catch {
        ConvertFrom-Json $_.errorDetails -AsHashtable
    }

    Write-Verbose 'Acquired token.'
    $token = ($response.content | ConvertFrom-Json).access_token
    $token = ConvertTo-SecureString -String $token -AsPlainText -Force
    Write-Output $token
}

$params = @{
    AccountID = '1234567891234567890123'
    ClientID = '12345678901234567890'

Ah, this is likely related to internet explorer not being on your local computer. I still have to push those changes to the powershell gallery.

[JosephMcEvoy]

The changes are pushed to the gallery. Please update your module and try again.

Hey,
So running that script in Powershell works but just plain running the command Connect-PSZoom -AccountID 'XXXX' -ClientID 'XXXX' -ClientSecret 'XXXX' in powershell doesn't

Annoyingly I'm using Rundeck and not Postman - I'll do some Googling on this one

Hello @JosephMcEvoy
I'm running into the same issue @AstroFish849 ran into. Were you guys able to find a solution?

[kaopectate]

ran that test "new-oauthtoken" script and it errored out on my win 10 machine, but worked fine on server. i believe this is due to changes in behavior of IE. when launched on win 10 machine it closes and launches new edge.

Also why are you not just using Invoke-RestMethod ?

[jwong00]

I think this is the issue I'm experiencing at the moment. It's not clear to me why IE is relevant to this issue, could someone please explain?

I've written a little test script that attempts the Connect-PSZoom with the accountid, clientid, and client secret. On my own machine, it works. On the server, it throws the same error messages others have screenshotted.
