How to print token in webform-confirmation.html.twig?

Question

I would like to output a submitted value as a token on the confirmation page through the twig. The token works just fine when added into the message box of webform as:

[webform_submission:values:score_percentage]

But I can't seem to get the same value to output through the twig. I have tried:

{{ webform_token('webform_submission:values:score_percentage') }}
{{ webform_token('[webform_submission:values:score_percentage]') }}
{{ drupal_token('webform_submission:values:score_percentage') }}
{{ drupal_token('[webform_submission:values:score_percentage]') }}

But they all just print the token itself, like:

webform_submission:values:score_percentage
[webform_submission:values:score_percentage]
[webform_submission:values:score_percentage]
[[webform_submission:values:score_percentage]]

I saw another post about (what I think is) the same thing here? But I haven't been able to see my error...

As well as this old issue, which by the looks of it would be fixed now.

I have the latest versions of Twig Tweak (8.x-2.9) and Token (8.x-1.9) installed. Am I doing something fundamentally wrong here?

First, talking about your twig extension:

• {{ webform_token(....) }}
• {{ drupal_token(....) }}

I've never seen drupal_token twig ext so let it out of here. or you guys can comment to help me update this answer.

For webform_token function, the real back end function of it you can check from this file: webform/src/Twig/WebformTwigExtension.php line 102. (v5.23.0). And it said that

public function webformToken($token, EntityInterface $entity = NULL....) {
  // Allow the webform_token function to be tested during validation without
  // a valid entity.
  if (!$entity) {
    return $token;
  }
  ...bla...bla
}

Mean that, if your code not given entity, it will return a string that you inputed. and the result will be like what you did.

Back to your case If you look into webform/templates/webform-confirmation.html.twig template file, you can see the Available variables:

• progress: Progress bar.
• message: Confirmation message.
• back_url: URL to the previous webform submission.

And the others Available variables can found at template_preprocess_webform_confirmation() of this file: webform/includes/webform.theme.template.inc. And they are

• webform,
• webform_submission,
• source_entity.

So, it mean that you can use {{ webform_submission.data.field_name }} in webform-confirmation.html.twig template file; instead of using token like the way you did above.

*Note: Try to avoid using twig extension in twig template would make you easier in debugging and maintenance.
