Connect to null failed: null

When i'm clicking on TEST CONNECTION button i'm getting: Connect to null failed: null

The credentials are fine since it recognizes my AKS clusters when i'm putting them.

Hi,

I am also facing similar issue with plugin version 0.4.1, Jenkins version 1.150.2, error logs below.

Same here. @mordf @aysahu What version of AKS do you use? I use 1.12.4.

[aysahu]

@torumakabe I am using 1.11.5 with VNET enabled.

[mordf]

I’m also using 1.11.5

[mordf]

I’m also using 1.11.5

[kristianhald]

We used AKS version 1.11.2, then upgraded to 1.11.6 to try an fix the issue.
Also tried creating a Jenkins server using the Microsoft template from Azure Marketplace with an AKS 1.12.4. Same error.

When I press the 'Test Connection' button, I can see that I get an error in the Activity Log for the resource group:

[torumakabe]

@kristianhald I got the same message "Could not find role name clusterAdmin". So I tested all versions of API by calling them directly. Then, 2018-08-01-preview only failed with the same error.

[aysahu]

Hey,

Anyone is working on our issue or it is just no body is listening us ?

[torumakabe]

@aysahu It seems the cause is that this plugin dynamically get the latest version API of AKS. The latest preview API published last week and it does not support get accessProfile. Azure team is making a hotfix to mitigate this issue.
jenkinsci/azure-acs-plugin#16 (comment)

[aysahu]

@torumakabe Thanks for information.

[mordf]

@torumakabe Thanks a lot for the update

[kristianhald]

Our Jenkins is working again with AKS.

Azure has deployed a hotfix for the latest API change.
https://github.com/Azure/AKS/releases/tag/2019-02-07

As I understand the change, they have made an endpoint, deprecated instead of removing it completely. The endpoint will be removed at a later date, so the plugin will probably need an update for this.

[mordf]

Working for me as well, closing the issue.
