Invoke-MgGraphRequest can't handle URI with #

[julmsy]

Hello,

I would like to use the Invoke-MgGraphRequest cmdlet to request Guest users. Guest users' UPN contains '#' characters. Example: first.last_foo.com#EXT#@contoso.onmicrosoft.com

$upn = first.last_foo.com#EXT#@contoso.onmicrosoft.com
Invoke-MgGraphRequest -Method GET -Uri https://graph.microsoft.com/beta/users/$upn
Invoke-MgGraphRequest : GET https://graph.microsoft.com/beta/users/first.last_foo.com
HTTP/1.1 404 Not Found

If I request the same URI on MS Graph Explorer, it works well. It seems that Invoke-MgGraphRequest cut the URI at the first '#' character.

I've tried different variations, but issue persists:

Invoke-MgGraphRequest -Method GET -Uri "https://graph.microsoft.com/beta/users/$upn"

$uri = 'https://graph.microsoft.com/beta/users/first.last_foo.com#EXT#@contoso.onmicrosoft.com'
Invoke-MgGraphRequest -Method GET -Uri $uri

Could you please have a check and fix it?

Module version tested: 1.20.0 and 1.25.0.

Best, julmsy

Hi @julmsy , have you tried to URL encode the # sign? The Graph explorer tool will automatically URL encode that.

Yeah, good call Ray.

Replace # with %23

$uri = 'https://graph.microsoft.com/beta/users/first.last_foo.com%23EXT%[email protected]'
Invoke-MgGraphRequest -Method GET -Uri $uri

Just out of curiosity though, is there a reason you can't use Get-MgUser? This works out of the box and will retrieve the same sort of info e.g.

$upn = "first.last_foo.com#EXT#@contoso.onmicrosoft.com"
Get-MgUser -UserId $upn

It's no big deal if you have a good reason to use Invoke-MgGraphRequest, I'm just wondering if you had a reason.

Perhaps an idea to use [System.Web.HttpUtility]::UrlEncode(“the raw URL you want to pass to Invoke-MgGraphRequest”) instead of the raw URL itself - that way any characters with special meaning will be translated

Yeah, good call Ray.

Replace # with %23

$uri = @.***'

Invoke-MgGraphRequest -Method GET -Uri $uri

Hello everyone,

Thanks for the suggestion @RayGHeld, it works like a charm. I hadn't thought of encoding in HTTP format.

$upn = $_.Value -replace '#','%23'
$response = Invoke-MgGraphRequest -Method GET -Uri https://graph.microsoft.com/beta/users/$upn

@SeniorConsulting, well I can use Get-MgUSer right, but using Invoke-MgGraphRequest is better to handle exceptions. I'm able to get the HTTP code, and depending of the answer (404, throttling, etc.) I can play different scenarios. Here is part of my code:

Try
{
    $response = Invoke-MgGraphRequest -Method GET -Uri https://graph.microsoft.com/beta/users/$upn
}
Catch [Microsoft.Graph.PowerShell.Authentication.Helpers.HttpResponseException]
{
    $statusCode = $Error[0].Exception.Response.StatusCode.value__

    If ($statusCode -eq 404)
    {
        [...]
    }
}
