Chromium cannot visit https without valid certificate without a lot of steps. You should tunnnel your dev server:
ngrok http 8000
Now add ngrok url to ALLOWED_HOSTS
Chromium will not visit https://localhost:8000, so run
brew install stunnel
Add ssl_proxy file
pid=
cert=/usr/local/etc/stunnel/stunnel.pem
foreground=yes
debug=7
[https]
accept=8000
connect=8001
TIMEOUTclose=1
Start
sudo stunnel ssl_proxy

A PDF/A document is just a PDF document that uses a specific subset of PDF that is designed to ensure it is 'self-contained'. It's not permitted to be reliant on information from external sources (e.g. font programs and hyperlinks).
From wikipedia:
Other key elements to PDF/A compatibility include:
- Audio and video content are forbidden.
- JavaScript and executable file launches are forbidden.
- All fonts must be embedded and also must be legally embeddable for
unlimited, universal rendering. This also applies to the so-called
PostScript standard fonts such as Times or Helvetica. - Colorspaces specified in a device-independent manner.
- Encryption is disallowed.
- Use of standards-based metadata is mandated.
