UI pages cause SCOM Console to close with unhandled exception (crash) #2
Comments

It looks like your SCOM server is struggling to access/resolve www.mpcatalog.net - do you have a firewall in place? Are you able to browse to www.mpcatalog.net/CatalogRepo from your SCOM server? It should forward you to a GitHub page which will display an error but you should see the URL change. |

@ChrisHeitkamp , sorry for the delay on getting this fix in place. A new build (detailed below) has been created that has more robust error handling, it should much more gracefully handle the lack of an internet connection. Links to the beta version of the build are at the bottom of the comment. The test build has been created that allows for the setting of a proxy via 3 registry keys. Additionally it allows for a direct URL to be used for connection to GitHub, without the use of the MPCatalog.net redirect. The keys can be seen in my branch at: https://github.com/MPCatalog/scom-community-catalog-ui/blob/work/1.0.2.x-bug-fixes/Community.ManagementPackCatalog.UI/Models/GitHubRepository.cs#L114 Proxy configuration has a key for each of the following:
Repo URL configuration has a single key of:
The updated version of the pack can be found here: Both registry configuration examples are available here: |

The beta release for this build is at the below url, the testing I have performed has passed, but I do not have an actual proxy environment and am unable to do a full functionality test. |

hi, tested with 1.0.2.1 - no success. Same error as before. - No Exception, console keeps functioning. This is my registry setting. - Correct? Ruben |

Thank you for testing,
I do not have a proxy in my environment and was not able to test as well as
I would have liked. I will look through the code again and may need to
find a sample proxy server to test with.

Another option could be adding debug code to your solution. I am happy to run it and provide trace information.
Let me know :-)
|

The code is instrumented with ETW logging, it can be viewed with perfview,
as well as a custom tool I've written to make it quicker to trace.
I'm out of the office for the night but I'll make sure tracing is in all
the necessary places tomorrow and send over some better details.
Thanks,
Nathan

Sure, no problem. - Have a good rest :-) |
|
Just i tip for others. I just found out i had the same errors while the sites mentioned are reachable. |
Symptom:
Open the "Discover Community Packs" view causes the SCOM Console to crash with an unhanded exception.
Description:
Before the crash a pop up screen shows up with:
"An error occurred while sending the request"
The crash is reproducible.
Crash details are given below.
Note that the Console on this machine does not have internet access, hence a prerequisite is not met. Still the console crashing is kind of unexpected...
SCOM Version: 2012 R2, UR12
MP Version: 1.0.2.0
Exception Details:
