Uuid in blueprint causes false duplicate page error

[luca]

When a call to page.uuid is present in a blueprint and a new draft of this specific blueprint is created in the panel, it shows

Error: A page draft with the URL appendix "..." already exists.

But the page is created anyway and shows up in the pages section when refreshing the panel after cancelling the dialog.

I tried a fresh starterkit, but everything works as expected there.

Then I tried to narrow down where the error comes from:

• disabling all plugins
• removing all page models
• creating a page method with a Uuid and an appendix and calling it instead of page.uuid in the template

Nothing worked. The error persists and I don’t know where to look further.
I am grateful for any ideas, what I could try next.

When a call to page.uuid is present in a blueprint

Please post the blueprint with this method

And which Kirby version are you using?

@texnixe

Please post the blueprint with this method

sections:
  fields1: 
    type: fields
    fields:
      test:
        type: info
        text: "{{ page.uuid }}"

@texnixe

And which Kirby version are you using?

I’m using Kirby 3.8.3.

Strange thing is, it seems to be enough that the page.uuid (or also page.uuid.id) is present anywhere in the blueprint – i.e. in an info field, in the help: prop of any other field and even as a data argument in Bnomei’s Janitor Plugin:

button_copy_id:
  type: janitor
  command: 'janitor:clipboard --data {{ page.uuid.id }}'
  label: 'Copy Page ID to Clipboard'
  progress: Copied!
  icon: copy

I could reproduce the problem in my not so fresh Starterkit, just surprised that you couldn’t. Need to test later tonight in a fresh kit.

To me, that smells like a bug.

Thanks for checking. It is not urgent to me, just kept bugging me…

Hi @texnixe
the error didn’t show in my starterkit because I forgot to set

`languages' => true

in the config, as in my main project.
If set, the error shows in a fresh starterkit.

As I now know how to reproduce the error, would it be of help if I filed an issue on github?

Yes, please. My Starterkit is multilang as well-

Hi, I encounter the same error but I do not use page.uuid in the bleuprint affected! If this has been solved meanwhile, it would be great to have the solution posted here.

@luca Did you file the issue and where can I find it?

Thanx a lot!

[texnixe]

page.uuid cannot be used in blueprint definitions in multi-lang setups

There is a workaround suggested in the issue as well

[luca]

you just beat me to the answer, @texnixe

Thank you @texnixe for the link! Meanwhile I analyzed my code and found the page.uuid causing the error in one of my custom models (instead of the blueprint …) where I take the UUID of the page to find out if there are any other pages refering to it (which of course do not with a page currently being created!):

$uuid = $this->uuid()->toString();

Changed it according to @bastianallgeier ’s suggestion in the issue mentioned above to:

$uuid = (string) $this->content()->get('uuid');

Works!
