No we haven't tried disabling Varnish - the PDF was printing fine on 2.4.1.

Ah, ok, I think I was wrong on that, I just read your error again, and I don't 
think that was it.

Have you tried disabling Varnish?  Did you just upgrade to 2.5 and this 
starting happening? It wasn't happening on 2.4?

Blake, thank you.

We tried adding into the NGIX config the following

add_header 'Referrer-Policy' 'origin-when-cross-origin';

But this hasn't solved the problem.

"Referrer Policy:origin-when-cross-origin"

I think that's it right there. I wish I could remember the details, but I've 
seen this before, there's something in one of the URLs being served that's 
breaking the cross origin rules. If I remember right, the counsel did show some 
errors and one of them had a localhost or something in a URL being served.

Blake,

No other errors other than the 422 error returned by the server.

We do, however, have a Varnish caching server also running as well. But not 
sure if this has anything to do with the printing problem.

Do you see any errors in the Chrome Dev Tools Counsel when you hit that page?

Subject: [Archivesspace_Users_Group] Error on v2.5.0 PUI print PDF

Dear Colleagues,

Does anyone have a solution to the problem we have encountered when 
implementing the AS PUI on a NGINX web server? In the test environment, we 
receive the attached error message when attempting to print any finding aid in 
Chrome or Safari browsers, although it works OK in Firefox.

Our technical staff have identified the probable cause as our use of NGINX, as 
opposed to the Apache webserver.

In the AS notes 
https://github.com/archivesspace/tech-docs/blob/master/provisioning/https.md#nginx,
 there are examples configuring Apache, but there is a “FIXME Need nginx 
documentation” note where the Nginx documentation should be.

Can someone provide us with the NGINX documentation and especially 
configurations to fix the printing issue?

I am including below an earlier thread related to the issue.

Thanks,

Just for the record: we were missing these two lines documented in 
README_HTTPS.md example in our apache config:

       RequestHeader set X-Forwarded-Proto "https"
       ProxyPreserveHost On


After adding those lines it appears to work properly.

Also discovered that PDF print thru SSL proxy does work in Firefox after 
googling “authenticity token proxy ssl”
and seeing title of this Rails issue:

 CSRF protection prevents some webkit users from submitting forms · Issue 
#21948 · rails/rails<https://github.com/rails/rails/issues/21948>

I’ve been seeing the bug in Safari, and you’ve been seeing it in Chrome. Both, 
I believe, are webkit based.

Long discussion thread that I haven’t digested yet, so I’m not sure if that is 
the problem here.
That same google search brings up some other issues that may be related to not 
passing all of the headers thru proxy.

Thanks. Yes: I’m still seeing the problem. No: no solution so far.
The fact that I was only seeing it on production limited my ability to debug.
Now that you’ve found it’s linked to SSL proxy, I will try to set up test 
machines to reproduce the problem.

Update: we were able to identify that this error was happening only when 
running the application over SSL. Accessing the site over non-SSL allowed the 
print function to work.

Hi Aspace!
I saw this post on the user group but was not able to find the thread in my

We are seeing this same error and we are running v.2.2.2 However, the error 
seems to be browser specific as it only happens in Chrome. Here's the log

Steve, were you ever able to find a solution for this? Has anybody else 
encountered this error when trying to print a PDF of a collection in Chrome?
Thanks,
