[Blue Ocean] API and UI URL mismatch behind reverse proxy

[Javier Martín Caro BEEVA]

Hi there!

We have set up jenkins blue ocean behind a nginx reverse proxy and configured successfully the prefix in the url to <URL>/jenkins. Despite of this, when we access to the blue ocean ui in <URL>/jenkins/blue and try to access some pipeline, a 422 (unprocessable entity error) is displayed in the browser debugging console and a white screen is shown.

The URL in the browser is like the following (note the encoded space):

https://<URL>/jenkins/blue/organizations/jenkins%20/<pipeline>/activity

When we call the blue ocean API for organizations the following information is shown (https://<URL>/jenkins/blue/rest/organizations/):

[{"_class":"io.jenkins.blueocean.service.embedded.rest.OrganizationImpl","_links":{"pipelines":{"_class":"io.jenkins.blueocean.rest.hal.Link","href":"/blue/rest/organizations/jenkins /pipelines/"},"self":{"_class":"io.jenkins.blueocean.rest.hal.Link","href":"/blue/rest/organizations/jenkins /"},"user":{"_class":"io.jenkins.blueocean.rest.hal.Link","href":"/blue/rest/organizations/jenkins /user/"},"users":{"_class":"io.jenkins.blueocean.rest.hal.Link","href":"/blue/rest/organizations/jenkins /users/"}},"name":"jenkins "}]

Note the white space in the organizations href after /jenkins /pipelines.

If we call to https://<URL>/jenkins/blue/rest/organizations/jenkins/pipelines/<pipeline>/runs/ the following message is shown:

{

  "message" : "Organization jenkins not found",

  "code" : 422,

  "errors" : [ ]

}

But if we force the organization to be jenkins%20 (https://<URL>/jenkins/blue/rest/organizations/jenkins%20/pipelines/<pipeline>/runs/) the information is displayed correctly.

Can someone help us to configure the proper name for the organization? We thought it was the jenkins url in the settings page but this is set to https://<URL>/jenkins/. 

Old UI is working properly for all pipelines, folder organizations and bitbucket team jobs.

Thank you and regards!

Hi Javier,

Hmm, certainly sounds like something is up. How did you install Blue Ocean? If you built it from source could you try to install it from the experimental update center and try again? 

We are performing weekly binary releases on the path to the beta release and you may have a snapshot where some key things (such as path encoding) was not working correctly.

Sorry for not responding sooner as I've been traveling for work.

The "dogfood" instance runs begind nginx at the moment (aside: there have been some problems with timing around SSE, but this sounds like you haven't got that far). 

so the first /jenkins resolves to the "classic" UI? 

It looks like nginx is stripping off the space somehow... 

I'll see if we can dig up a config that works and compare. 

are you able to share you nginx proxy config?

also, if you access direct, the extra encoded space, does that appear?

Hi there,

It is because your Jenkins instance is in spanish!.

There is this bit of code https://github.com/jenkinsci/blueocean-plugin/blob/master/blueocean-rest-impl/src/main/java/io/jenkins/blueocean/service/embedded/rest/OrganizationImpl.java#L40 

And a quick grep

ivan@MacBook-Pro ~/w/jenkins/core/src/main/resources/jenkins/model (master)$ grep -R -E 'Hudson.DisplayName=.* $' .

./Messages_es.properties:Hudson.DisplayName=Jenkins

I created PR https://github.com/jenkinsci/jenkins/pull/2471 to fix it in Jenkins, 

and also JENKINS-36907 to track it in Blue Ocean.

Switching your language should fix this.I imagine this will be changed in Blue Ocean quickly too.

haha - this is not the first time i18n has bitten URLs. 

Although in this case the extra space is incorrect (but Blue Ocean just happens to use that in the URL whereas classic does not).

That… seems weird to be honest.

[Javier Martín Caro BEEVA]

Wow, I really appreciate it, I wouldn't found it in a million years! :)

Thank you all.

[Michael Neale]

Javier - its this type of thing that Ivan excels at. 

"hey Ivan I am seeing this really odd thing...."

Ivan: "Oh hahaha I know exactly what that is". 

Everyone needs an Ivan.

I'm using Jenkins 2.19.4 and still has this issue while on Spanish language.

When will this issue be fixed?

I've re-opened JENKINS-36907 and submitted a pull request that should fix this regardless of any errors in the translation. If all goes well it should be in next weeks Blue Ocean beta.

A fix should be available in Blue Ocean beta 13 next week.
