GraphAPI GetAccessTokenFromRefreshToken missing parameter

[kennyvv]

I was trying to use the GraphAPI and AuthenticateUsingRefreshToken, however i get the following exception.

KoenZomers.OneDrive.Api.Exceptions.TokenRetrievalFailedException: Failed to retrieve OneDrive access token. Additional information: AADSTS7000218: The request body must contain the following parameter: 'client_assertion' or 'client_secret'. Trace ID: ae843ab5-b298-4ff5-bd4e-7f52660a2300 Correlation ID: 8ce4b213-b349-47b2-8fc6-a21928a18c8b Timestamp: 2019-03-06 12:58:00Z at KoenZomers.OneDrive.Api.OneDriveApi.PostToTokenEndPoint(QueryStringBuilder queryBuilder) at KoenZomers.OneDrive.Api.OneDriveGraphApi.GetAccessTokenFromRefreshToken(String refreshToken, String[] scopes) at KoenZomers.OneDrive.Api.OneDriveGraphApi.GetAccessTokenFromRefreshToken(String refreshToken) at KoenZomers.OneDrive.Api.OneDriveApi.AuthenticateUsingRefreshToken(String refreshToken) --- End of inner exception stack trace ---

I thought i might have to set the client secret, however i can't set the property.
What is the issue here?

Sorry for the late follow up on this one. Can you try this again using the latest version? I remember fixing something which could be related to this around the time you reported it. If the issue still exists and you're still in need for a solution, it would help if you can share a Fiddler capture of the request being made via e-mail with me. Don't upload it here.

When I use custom redirect url.
Must provide client_secret in GetAccessTokenFromAuthorizationToken and GetAccessTokenFromRefreshToken.

public class MyOneDriveGraphApi : OneDriveGraphApi
{
    public MyOneDriveGraphApi(string applicationId, string clientSecret) : base(applicationId, clientSecret)
    {
        OneDriveApiBaseUrl = GraphApiBaseUrl + "me/";
    }

    protected override async Task<OneDriveAccessToken> GetAccessTokenFromAuthorizationToken(string authorizationToken)
    {
        var queryBuilder = new QueryStringBuilder();
        queryBuilder.Add("client_id", ClientId);
        queryBuilder.Add("scope", DefaultScopes.Aggregate((x, y) => $"{x} {y}"));
        queryBuilder.Add("code", authorizationToken);
        queryBuilder.Add("redirect_uri", AuthenticationRedirectUrl);
        queryBuilder.Add("grant_type", "authorization_code");
        queryBuilder.Add("client_secret", ClientSecret); // Add this
        return await PostToTokenEndPoint(queryBuilder);
    }

    protected override async Task<OneDriveAccessToken> GetAccessTokenFromRefreshToken(string refreshToken)
    {
        var queryBuilder = new QueryStringBuilder();
        queryBuilder.Add("client_id", ClientId);
        queryBuilder.Add("scope", DefaultScopes.Aggregate((x, y) => $"{x} {y}"));
        queryBuilder.Add("refresh_token", refreshToken);
        queryBuilder.Add("redirect_uri", AuthenticationRedirectUrl);
        queryBuilder.Add("grant_type", "refresh_token");
        queryBuilder.Add("client_secret", ClientSecret);
        return await PostToTokenEndPoint(queryBuilder);
    }
}
