Hi,
I'm attempting the following module, where you need to install an unmanaged package.
https://trailhead.salesforce.com/modules/lightning_app_builder/units/lightning_app_builder_custom_comps 
I have followed the following help article's steps exactly
https://force.desk.com/customer/portal/articles/2710899-installing-a-package-or-app-to-complete-a-trailhead-challenge?b_id=13478

However, the unmanaged package is still being installed to my overall Salesforce instance, NOT to my "Trailhead Playground".

Given the challenge checks against the Playground, it is impossible currently to complete the challenge.
Is this a common problem & if so how do I solve it?
Thanks,
Matt



 

I'm having a problem getting the test api login to grant me an access_token.   I am POSTing my request to https://test.salesforce.com/services/oauth2/token and here is my Request Header, I shortened the assertion value for brevity:

POST https://test.salesforce.com/services/oauth2/token HTTP/1.1
Content-Type: application/x-www-form-urlencoded; charset=utf-8
Host: test.salesforce.com
Content-Length: 415
Expect: 100-continue
Connection: Keep-Alive

grant_type=urn%3Aietf%3Aparams%3Aoauth%3Agrant-type%3Ajwt-bearer&assertion=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3[ ... ]ODMzN30.OE8FouPsqAXudnKgSZ0NeWnVjA1LYPtLgk4GXMx2kno

Every time I submit this, I'm getting the following Response:

This is being written in C# .NET 4.5.1 using the JSON Web Token Handler provided by Microsoft:

public void Login()
{
            var token = GetAuthToken();
            const string uri = "https://test.salesforce.com/services/oauth2/token";
            var httpWebRequest = (HttpWebRequest)WebRequest.Create(uri);
            var authRequest = new HttpClient();

            var authContent = Uri.EscapeDataString("urn:ietf:params:oauth:grant-type:jwt-bearer");
            var authToken = Uri.EscapeDataString(token);

            WebResponse response = null;
            try
            {
                var responseMessage = await authRequest.PostAsync(uri, new StringContent(string.Format("grant_type={0}&assertion={1}", authContent, authToken), Encoding.UTF8, "application/x-www-form-urlencoded"));

                var test = "test";
            }
            catch
            {
                throw;
            }
            finally
            {
                if (response != null)
                {
                    response.Close();
                    response = null;
                }
            }
}

private static string GetAuthToken()
{
            var securityKey = GetBytes("security key I was provided");

            var tokenHandler = new JwtSecurityTokenHandler();
            var now = DateTime.UtcNow.ToUniversalTime().Subtract(new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).TotalMilliseconds + 6000;
            var tokenDescriptor = new SecurityTokenDescriptor
            {
                Subject = new ClaimsIdentity(new List<Claim>
                                                {
                                                    new Claim("iss", "my client id"),
                                                    new Claim("aud", "https://test.salesforce.com"),
                                                    new Claim("prn", "user@domain.com"),
                                                    new Claim("exp", now.ToString(CultureInfo.InvariantCulture))
                                                }),
                                                AppliesToAddress = "https://test.salesforce.com",
                TokenIssuerName = "my client id",
                SigningCredentials = new SigningCredentials(
                    new InMemorySymmetricSecurityKey(securityKey),
                    "http://www.w3.org/2001/04/xmldsig-more#hmac-sha256",
                    "http://www.w3.org/2001/04/xmlenc#sha256")
            };

            var token = tokenHandler.CreateToken(tokenDescriptor);

            return tokenHandler.WriteToken(token);
}

Any ideas or suggestions would be greatly appreciated.
