barnett2 sorry to hear that

Could you please
1. Check that all the blue ocean plugins installed without failures
2. Post a list of all of your installed plugins as a comment to this ticket
3. Capture a HAR file of the failed browser load and email it to me at jdumay@cloudbees.com

James, thanks for looking.

1. As far as I could see during installation, there were no errors reported.  I don't know where to look to find any errors now.  I've attached images showing the plugins installed that match pattern "ocean".

2. Will add the list of all plugins in a second comment in a minute.

3. HAR file will be sent shortly.

Hopefully this is readable...

This effects the default blue ocean docker image. It means the default image does not work at all.

bitwiseman there will be a new docker image out sometime today for Blue Ocean 1.1 - lets wait for that then confirm we can reproduce this problem.

ydubreuil this is the symptom of the problem you are fixing with the docker image

https://github.com/jenkinsci/blueocean-plugin/pull/1148

Right, so PR-1148 which is now merged should fix the issue. I followed up with PR-1151 so rtyler will be able to trigger a new build of the image.

We've deployed a new docker image jenkinsci/blueocean:1.1.0-77aad2de8dbb that contains a fix for this issue.

Thank you ydubreuil and rtyler for your help.

I understand that version 1.1.1 should address the issue. I've installed the available updates and they all showed as applied [some with a message that they will activate after restart]. I restarted Jenkins, however, I still get the "loading..." bar and console has 2 errors:

This looks similar to the original error, but not identical.

Please advise.

Thank you.

I still get similar errors as before while using the 1.1.1 version. Exact error messages attached. Please advise.

Thanks - ill have someone perform a deep investigation now.

Probably cleaning up the browser cache will fix the issue.

I cleared "Cached images and files" [399MB worth], closed Chrome, opened Chrome, accessed Jenkins and clicked "Open Blue Ocean". I get what appear to be the same errors as before.

Interesting. When I click on each error, an additional line shows up. I've attached the errors again with this additional/last line.

I don't know if that is helpful or not.

barnett2 a few other things to try - given this isn't related to 1.1 or 1.0.1 - there is a LOT of code that has changed so may need to broaden investigation. Could you do a fresh install of jenkins on your desktop (or somewhere) with blue ocean 1.1.2 (which is just out) - and try in the same browser? have you tried other browsers? Is there some content/ad blocker that is possibly changing something? 

barnett2 hmm, the only thing I can think of is some plugin mismatch. Sometimes the plugin manager doesn't install plugins correctly.

Could you try the following:

1. Shutdown Jenkins
2. In your home directory "rm -rf plugins/blueocean*"
3. Start Jenkins
4. Reinstall Blue Ocean from the plugin manager

jamesdumay Shutting down, cleaning up and removing has had no impact. Same errors as before.

michaelneale I have a separate Jenkins instance running that has fewer plugins and way fewer jobs. It does not have this same issue. It is upgraded to the latest tools. I have not previously tried our production server with any other browsers. After the above shutdown, remove, restart, re-install steps above, I tried with Internet Explorer. Clicking the "open Blue Ocean" link loads and loads and.... and never seems to come back. I see no errors in the console or under network tabs. Similar behavior as on Chrome; blue bar showing loading, loading, ....

barnett2 before performing a clean install, could you perhaps check your Jenkins logs and see if there are any errors logged from the "JenkinsJSExtensions" class? I believe jamesdumay is right and this error is caused by a problem building the list of plugins that Blue Ocean consumes but would be good to get more insight from your logs if it's there.

barnett2 perhaps you could also "view source" in your browser and find the first script block on the page. You should see a line like this:

// State Preloader: io.jenkins.blueocean.config.JenkinsJSExtensionsStatePreloader
        setState('jsExtensions',

With a very long list of plugins after it. If you could paste or upload that snippet here that would help too.

I have no specific errors from the JenkinsJSExtensions class.

I do not have any entry matching pattern "jsExtensions" in the source that has downloaded.

cliffmeyers Sent via email.

Examining the page source content, I've noticed that the following preloader entries are missing:

// State Preloader: io.jenkins.blueocean.config.BlueOceanConfigStatePreloader
setState('config', { ... });
// State Preloader: io.jenkins.blueocean.config.JenkinsJSExtensionsStatePreloader
setState('jsExtensions', [ ... ]);

barnett2 I checked your plugin list and it appears that the "Config API for Blue Ocean" (aka "io.jenkins.blueocean.blueocean-config") is missing from the list. If it were not installed, it would explain the absence of this important data. Could you check to see if it's installed and if not, try adding it?

cliffmeyers I'm pretty sure it was there previously, but is not there now [after remove / restart above?]. I've added it, and now the error is different. I did not restart Jenkins as the plugin page did not dictate it was required.

First error:
/blue/rest/i18n/blueocean-web/1.1.2/jenkins.plugins.blueocean.web.Messages/en-US Failed to load resource: the server responded with a status of 404 (Not Found)

Second error:

Perhaps you could post the list of "Blue Ocean" plugins installed in your instance? I'm concerned that if one was missing previously that the full list may not be correct or you may have incompatible versions of other plugins. In particular check that "Web for Blue Ocean" is version 1.1.2 and not an older version.

cliffmeyers Please see below. I noticed a little bit ago that "Blue Ocean" isn't among the installed list. Perhaps removed during the remove / restart ... I have not added it, yet. Will wait for your feedback.

Yes, please install "Blue Ocean" as it should pull in all the other plugin dependencies required for proper operation. After install / restart you should see the "available plugins matching blue ocean list" slim down considerably if not entirely.

cliffmeyers Thanks. I don't know which part of this solved the issue, but one [or more] of the following have resolved the problem and all errors are now gone:

1. Stop Jenkins, remove plugins/blueocean*, Start Jenkins, install some of the Blue Ocean components – apparently, I missed some.
2. Restart Jenkins.
3. Install the "Config API for Blue Ocean"
4. Install the "Blue Ocean" plugin – apparently missed during a prior step
5. Restart Jenkins

One thing I note is that the [Blue Ocean] link across the top of the Jenkins header is removed and is replaced by a "Open Blue Ocean" link in the left-hand navigation pane.

Not 100% sure which of the above steps solved the issue, but Blue Ocean is now working.

Thank you.

Glad that it's working! The "Open Blue Ocean" link was moved to the left navigation (in 1.1, IIRC) based on some user feedback.

From the issues you were facing, it sounds like the following problems occurred:
1. "Config API for Blue Ocean" was removed at some point, which led to the "Must call ExtensionStore.init() " error
2. "Web for Blue Ocean" was using an older incompatible version, which led to the 404 for the blueocean-web@1.1.2 I18N bundle.

Please let us know if you have any further issues.

yes plugins that bring in other dependencies can be tricky when you switch between beta versions, or want to remove (it is never easy). I suspected it may be this issue. 

If you install the "Blue Ocean plugin" from the UC it will bring in the correct dependencies.
