App cloning failed for some internal reason

Your application [TargetAcceso] cloning has failed for some internal reason.

Most probably we’re already aware of the failure and are working on it, but feel free to create a topic at our to inquire about the progress.

The AppID: 147F3E51-266A-AAC4-FF2B-DFE9F84FD200

I tried two times V15 and V16 but not cloning.

Thanks, Mario

Have you checked the log file in the Files section of your app? I believe it will be in the /logging directory.

Going to lock app ‘147F3E51-266A-AAC4-FF2B-DFE9F84FD200’ for cloning.

Thank you. This is very helpful. I created an internal ticket BKNDLSS-28804 to investigate the issue.


Hi @Mario_Ghersi ,

We fixed problem on our side. Could you please try to clone your app one more time and confirm that problem gone?

Regards, Andriy

I found the V15 and V16 ready clone. Now I execute V17 to check if it’s working proporly

Thanks, Mario

The test clone version was V17 and failed again.

Hello @Mario_Ghersi

As I see from the application-clone.log file there were some hang out. I have tried to clone your app one more time and it works now.
