[dmatej]

Jenkins and plugins versions report

Jenkins 2.514
Java 21
Docker Plugin 1274.vc0203fdf2e74

What Operating System are you using (both controller, and any agents involved in the problem)?

Ubuntu in your docker container

Reproduction steps

First seen on Devops ToolBox application on android, then I reproduced it using curl.
curl -u admin http://host:port/job/TCK%20Externals%20deploy/api/json

Expected Results

JSON response.

Actual Results

Html containing just a general error message (the client app was unable to parse it)

Oops!
A problem occurred while processing the request
Logging ID=f058ccc2-abdd-4be3-a247-cc181a15526b

And this stacktrace on the server:

which was followed yet by another one about uncaught exception causing ServletException which is probably not interesting.

Anything else?

I'm unable to duplicate the issue based on the information provided. I made guesses about the configuration and was unable to see the issue. I've attached the files that I used to try to duplicate the issue as a zip file for your reference.

Steps I took while trying to duplicate the issue:

1. Create a plugins.txt file that lists the exact plugins installed
2. Create a README file that can be executed to download Jenkins 2.514 and the plugins defined in plugins.txt
3. Run the README script with bash ./README and complete the setup wizard by installing no additional plugins
4. Configure the Jenkins controller with 0 executors and enable the JNLP listener port from the security settings
5. Configure a Jenkins cloud with Docker using the local docker installation that my account normally uses
6. Configure the agent template to use the Jenkins inbound agent template with Alpine
7. Create a job named "alpine" that runs a hello world Pipeline step
8. Run the job named 'alpine' and confirm that it allocates an agent and completes successfully
9. Create a job named 'alpine with space' as a copy of 'alpine' and confirm that it allocates an agent and completes successfully
10. Open the REST API JSON pages for each of those jobs and confirm that no stack trace is shown and the JSON looks reasonable

The files that show what I did are included in the zip file. I used username 'mwaite' with the password the same as the username

I was able to duplicate the issue by following the instructions in JENKINS-61699. I created a freestyle project and enabled "Define Docker template".
