I have the same issue. I will send you a JSON file as well.

monger39 - from the email you sent me I'm not seeing any of the missing data.

Does your browser's console log show anything? In the network tab, is anything red/failing?

Are you using the latest version of blueocean?

halkeye in my browber, I can see a (blue) progress bar. This goes up to say 80% quite fast. Then it still goes forward to

appr. 90% where is gets stuck forever (at least overnight).

I run on Windows (7-PRO) and use the following:

just upgraded Jenkins; from the log:

Searching through the Jenkins log for "blueocean", I did find a few lines that maybe could help??

If you'd need full logs, pls let me know
 

klm this should be fixed in 1.14.0

monger39 I didn't see any errors in any of the logs you have. Can you try 1.14.0 and if that fails, open a new bug with your javascript console log? (Right click, inspect element, click console tab, open blueocean (or refresh page)).

halkeye : I have updated all Blue Ocean plugins to 1.14.0 but the problem remains. I have tried using 3 browsers with identical result.
The script console gives a number of errors. As asked I will open a new bug report.

see: https://issues.jenkins-ci.org/browse/JENKINS-56662

halkeye - just confirmed that 1.14.0 does fix the problem I was seeing in Blue Ocean.

Hi, I want to comment here since I have met the same issue in the ticket on Blue Ocean version 1.21.0 with Jenkins version 2.204.2

The error in browser console is "Timed out waiting on module 'blueocean-pipeline-editor:jenkins-js-extension' to load."

And jenkins log will give the same error with David commented before:

If whole log is needed, I will add more.

Could you please help to check whether this is a new issue or the ticket hasn't been solved completed?

lixiaod2 For me, upgrading from Jenkins `2.204.2` to `2.222.1` (with Blue Ocean 1.23.2) fixed the hanging problem.
