Create new item - Item name error 'Only alphanumerical characters allowed'

[Laura López Senderos]

Hi everyone,

Since the lastest releases of Jenkins we're having a problem when creating new items. We always get the 'Only alphanumerical characters allowed' error when trying to create a new item.

We've tried from multiple browsers, changing our system language and the error persists. We don't know why this is happening suddenly and we can't find out a solutions :(

We've 14 projects created without problems, but for a month or so we're unable to create new ones.

Any help will be appreciated.

Thanks in advance.

Possibly the folder where you're creating those items has a character in its name that is outside the allowed set of characters?

Hi Mark,

The folder where every jobs are created is '/var/lib/jenkins/jobs'. This is the default folder and we've been able to create items on it since now.

Maybe some plugin update, or the jenkins instance update has broken something... We can't rename the jobs neither :/ It's like the regex that checks the name of the job is not working well.

Is there anyone having the same issue?

Thanks.

I've not seen any report of that issue from anyone other than you.

When I asked if a folder containing the job included an unexpected character, I was thinking of a Jenkins folder more than a directory on the file system.  The directory on the file system which represents that Jenkins folder would be inside a subdirectory or series of subdirectories of /var/lib/jenkins/jobs/.

If you don't use Jenkins folders to organize your jobs, then that is not the issue.

What version of Jenkins are you running that is broken?  What version of Jenkins were you running when it was working?

Our current Jenkins version is 2.176.2. We're not sure when it has started happening, because we've made some updates on plugins and Jenkins instance since the last job creation.

It's really strange because we've been able to create jobs with spaces, hyphens, underscores, lowercase, uppercase.... and without problems.

But now, we only type a letter, any letter, and the error message is shown. We've tried to follow the javascript code in browser developer console when typping a letter, but finally there's an ajax request and we can't see anything more.

I'm thinking on installing Jenkins CLI to try creating a Job from commands and if the error persists. This isn't the solution I would like to use but if it works we'll have to use it meanwhile.

Thanks.

Can you give a list of plugins and their versions that you have installed? Did you restart Jenkins after the upgrade of plugins?

There is an option to restrict job naming…do you have it checked on?

Thank you very much Shaun, you've hit right!

There's an option in Jenkins management to restrict the job names: manage jenkins -> configure system -> restrict project naming.

We've a pattern to allow only alphanumerical characters, but with some jenkins or plugin upgrade this pattern has been ignored and we had jobs with spaces on its names. After others upgrades the pattern has worked again, and the error in job name has appeared because of the existing jobs with spaces.

So the solution is:

- disable the restriction in job names

- change the jobs' names with spaces to remove the spaces

- enable again the restriction in job names

Thanks to all people who has answered our post and try to help us!
