Import Fails: "Error Unable to complete your request. The following exception occurred: null." When not authorized to GitHub

[karstengresch]

DM version 7.1.1, manual install (macOS 10.14.1).

Followed the automatic install, manual import steps.

After successful log in, went to the well hidden Hamburger dots menu at the left hand side, selected "Import project" and entered the URL

https://github.com/jbossdemocentral/rhdm7-loan-demo-repo.git

in the modal dialogue that shows up. Here one could selecting ""Show Authentication Options"" to enter GitHub credentials, but this is not mandatory or an obvious task to do.

An entry for the project in a selectable "card" then is displayed at the left hand side, that can be selected and the import can be started with selecting an "OK" button in the upper right corner (on 4K displays b.t.w. not very intuitive).

When not entering the GitHub authorization information by clicking on "Show Authentication Options", the import fails with the error message: "Error Unable to complete your request. The following exception occurred: null."

When entering the credentials, the import works fine.

It'd be good to either fix this problem in the product (better error description, make authorization mandatory or else) and/or correct the documentation that it might be needed to enter the authorization credentials.

Hi @karstengresch,

I tried to reproduce this on v7.2, but I can't. Are you sure this is related to Github credentials not being entered? The stacktrace looks like a problem with repository creation rather than a Github credential problem ....

Cheers,

Duncan
