Webform entity print attachment token doesn't work

I don’t completely understand this bug report or what “it doesn’t work” means on a technical level. That said is this something to do with this default configuration → ?

If that setting doesn’t lead to a solution, you need to update the issue summary. The steps to reproduce must be complete proceeding from installing Webform module.

Sorry, I updated the request, I hope it's more clear now

Is there a way to trigger the bug with only Webform? Could you please also talk about what I wrote in comment #3? What is the evidence pointing to Webform itself as having this bug as opposed to the other modules?

I don’t understand steps 6 and 7, and I don’t understand the actual behavior vs the expected behavior.

There is a way to trigger the bug with only Webform - generated file is not present in WebformSubmissionInterface $webform_submission

It would be ideal if you respond to all my questions, and also if you update the steps to reproduce to be as short and as simple as possible.

I updated the description.
I tried two different Rest handlers, both built into the Webfrom module, and Webform Remote Handlers, and the Attachment PDF value is missing in both cases

Ok. Let’s see if this is documented well enough for contributors.

I'm seeing exactly this problem with an 'Attached PDF' field (requiring Entity Print module → ) in a Webform - requiring Webform Entity Print (PDF) and Webform Entity Print (PDF) Attachment modules to be enabled. I'm not extending Webform with the Webform Remote Handlers module, so my instance is slightly simpler.

The token (for example) [webform_submission:values:pdf_version] is rendered as [webform_submission:values:pdf_version] in an email generated by a Webform Email handler, not the generated link to the PDF file (which would be expected behaviour).

I've been able to generate a link to the PDF using [site:base-url]/print/pdf/webform_submission/[webform_submission:sid]?view_mode=html&token=[webform_submission:token] but this doesn't generate the PDF file with the correct filename.

The issue is that the Attachment PDF element isn't available through the [webform_submission:values:*] token. Since I need to send the PDF to a remote endpoint, I created a custom token that encodes the Attachment PDF element in base64.
