Cordova Android application getting "invalid_client" from MobileFirst 8.0 server

Question

My Cordova IOS application integrated with IBM MobileFirst v8 works fine. However I face a weird issue with Android.

The scenario is, The user has to login into security check to access the application.

The challenge handler is called and credentials are submitted to (runtime/api/preauth/v1/preauthorize). I see in the logs security check is passed.

I can see the next call to authorization end point (runtime/api/az/v1/authorization)

However I see a difference between Android and IOS in the parameters passed to this end point.

Android

    response_type=code
    scope=
    client_id=
    redirect_uri=http://mfpredirecturi&isAjaxRequest=true&x=0.9217767383903592

The subsequent call to token generation end point fails for Android alone. /runtime/api/az/v1/token HTTP/1.1" 400 {status: 400, errorCode: "invalid_client", description: "Incorrect JWT format"}

IOS

    response_type=code
    scope=
    client_id=
    redirect_uri=http%3A//mfpredirecturi

WLAuthorizationManager.login(SECURITY_CHECK_NAME, credential) triggers /preauthorize call

cordova-mfp-plugin (8.0.2016110713) cordova-android (5.2.0)

my primary suspect is redirect_uri which is not encoded for Android alone. is the one causing the problem? is it possible to encode and send the redirect_uri from cordova application?

What is the first operation that triggered the preauthorize in your app? (resource request / obtain / login etc). We're trying to reproduce. Also, can you check the version of the cordova-mfp-plugin? — Nathan H, Dec 21 '16 at 07:13
WLAuthorizationManager.login(SECURITY_CHECK_NAME, credential) is the one that triggered the preauthorize. — Vignesh Sn, Dec 21 '16 at 13:03
I use the latest version of cordova-mfp-plugin (8.0.2016110713). — Vignesh Sn, Dec 21 '16 at 13:16
Could you also provide the version of `cordova-android`. Check by typing `cordova platform`. Add all the information by editing the question. — Nathan H, Dec 22 '16 at 12:36
I couldn't figure out this issue. No clue. Any help and pointers will be greatly appreciated. — Vignesh Sn, Dec 26 '16 at 09:22
@vinesh-sn if you are a customer, I suggest opening a PMR in the meantime. — Nathan H, Dec 26 '16 at 09:24
@IdanAdar I took this issue to my organization for validation. Will raise PMR soon. — Vignesh Sn, Dec 29 '16 at 11:35
@IdanAdar Is there any solution to this problem? We have also came across same problem. — Mohammad Ashfaq, Feb 18 '17 at 06:34
The PMR is still open. You can open another saying you experience the same. — Idan Adar, Feb 18 '17 at 06:35
@IdanAdar I am getting the same issue .. any solution ? If anyone opened a PMR then how can we check that ? — Gaurab Kumar, Apr 21 '17 at 13:36
Any update? was this fixed? We are having the same issue on one of our projects, can you share how this was resolved for you? — WiPhone, May 19 '17 at 13:46
Well I could not find a solution but if you need to have it running temporarily, I have found a hack. Change the time on your client device from T (Where T is the actual time) to T+15mins. Its just a temporary fix. — user3293079, Jun 09 '17 at 04:23

You can try newer MFP adapter plugin in your pom.xml

<build>
    <plugins> 
        <plugin> 
            <groupId>com.ibm.mfp</groupId>
            <artifactId>adapter-maven-plugin</artifactId>
            <version>8.0.2017021701</version> 
            <extensions>true</extensions> 
        </plugin> 
    </plugins>
</build>

This adapter plugin version works fine.
