Hi everyone,

I'm completely new to Dynamics 365 and specifically to Business Central. I was trying to make an Http call in sandbox container local, but what I got is httpclient.get() returned false.

when i try to installed and published to the sandbox online, it works. I don't know why not working on sandbox container local, can somebody help me?

here's my PowerShell script to create container

$accept_eula = $true

$containername = 'testing-bc2'
$navdockerimage = 'xxx.com/businesscentral/sandbox:XXXXX-au'
$appbacpacuri = ''
$tenantbacpacuri = ''
$additionalParameters = @()
if ($appbacpacuri -ne '' -and $tenantbacpacuri -ne '') {
    $additionalParameters = @("--env appbacpac=""$appbacpacuri""","--env tenantBacpac=""$tenantbacpacuri""")
}

$credential = get-credential -UserName $env:USERNAME -Message "Using Windows Authentication. Please enter your Windows credentials."
New-NavContainer -accept_eula:$accept_eula `
                 -memoryLimit 4G `
                 -containername $containername `
                 -auth NavUserPassword `
                 -Credential $credential `
                 -alwaysPull `
                 -doNotExportObjectsToText `
                 -usessl:$false `
                 -updateHosts `
                 -assignPremiumPlan `
                 -shortcuts Desktop `
                 -imageName $navdockerimage `
                 -additionalParameters $additionalParameters

Setup-NavContainerTestUsers -containerName $containername -password $credential.Password

here's my code

procedure FetchRandomUser()
    var
        Client: HttpClient;
        Response: HttpResponseMessage;
        Request: HttpRequestMessage;
        Header: HttpHeaders;
        Url: Text;
        ResponseText: Text;
        ResContent: HttpContent;
    begin
        Url := 'https://randomuser.me/api/';
    if Client.Get(Url, Response) then begin
            Message('SUCCESS');

            Response.Content.ReadAs(ResponseText);
            Message(ResponseText);
        end;
    if Response.HttpStatusCode() = 200 then begin

            ResContent := Response.Content();
            ResContent.ReadAs(ResponseText);
            Message(ResponseText);
    end;
        Message('httpstatusCode %1, reason%2', Response.HttpStatusCode, Response.ReasonPhrase);
    end;

I got HttpStatusCode = 200 but its throw an error

Your code works fine for me on my local container.

Perhaps it's a firewall issue?

Have you tried accessing that URL from a web browser or Postman from the machine hosting your container?

Sure, I used this:

$artifactUrl = Get-BCArtifactUrl -type sandbox -country gb -select Latest

$credential = New-Object pscredential 'admin', (ConvertTo-SecureString -String 'P@ssword1' -AsPlainText -Force)

New-BcContainer `

-accept_eula `

-containerName test `

-artifactUrl $artifactUrl `

-Credential $credential `

-auth UserPassword `

-updateHosts `

-enableTaskScheduler

As you're getting your database from a bacpac, you might want to check that the http client hasn't been disabled (although you would have got a message pop up): www.kauffmann.nl/.../

httpclient for my extension is enabled broo, but still not working on my local container. is there any possibility because of the image I used? I'm using image from PS script generated from BC Cloud.

Not sure why that would make a difference, but have you tried using my script? It will create a sandbox container on the latest release.

Something else you might want to try is to see if you can download a web page, if you can't you've got a networking / firewall issue.

Try these commands from PowerShell:

PS C:\windows\system32> Enter-BCContainer test

[TEST]: PS C:\Run> Invoke-WebRequest http://google.com -OutFile "C:\Run\test.html"

[TEST]: PS C:\Run> Get-Content C:\run\test.html

Hi guys, i'll ask here instead of starting a new thread because i'm facing a similar problem.

I did a test application sending a get request with .. HttpClient.Get(...url... , Response), and was all working fine, i did the same on my customer's BC (onPrem, same version as test environment) but it doesnt work, same code, same Url.
I tried every possible solution i found on the forums/blogs, no way out.

Interesting facts:
- if i try to change Url with https://www.google.com it still wont work, but if i go with http instead of https, it does work.
- i tried to go with http also for the original url, but didnt work
- if i try with the powershell command mentioned above "Invoke-WeRequest", it works with every url, either http or https.

so i'm really confused at this point, why shouldnt this work in my code aswell ?
