Error: Call to a member function Output() on null in Drupal\views_pdf\Plugin\views\display\PDF::buildResponse() (line 141 of modules/contrib/views_pdf/src/Plugin/views/display/PDF.php).

Created MR!3 for the issue mentioned, please review.
Thank you.

how can I replicate this error ?

Hello,
I just have this error with an 10.0.8 Drupal and with a 9.5.9 Drupal
My server have this configuration : Apache/2.4.54 (Unix) OpenSSL/1.1.1k PHP/8.1.6

My views are basic, I left the default configuration, my path is in the form /convention-impression.
The first time I generate the PDF view it works, but not after that.

What do others want as pieces of information ?

I have the same issue and found that if I clear the cache, I can run it again.

I had the same issue, the views_pdf was exporting to PDF only the first time and clearing the cache made it work again but only once.

I tried the patch in MR!3 but it was creating an error on the return $response...

So I disabled the cache on the PDF view and now it is working well everytime!

I had the "Tag based" and using "No caching" made it work.

Same for me emptying the cache or removing caching from the view removes the error

So to replicate this error, you leave the cache on and the view pdf will work only once the first time.

Disabling the cache completely on the view solves this issue for good.

Thank you for looking into this.
