URL Shorting with YOURLS not working when using PHP 8 or above on NGINX

[scsa20]

Describe the problem/question

When using PHP 8 or above the URL shorting option does not work (even though it still creates a shorten URL), this is the error that I get in the logs

It works just fine when the privatebin instance is set to use PHP 7.4.x

Did you use the FAQ section?

• Yes, I have read the FAQ and I found no solution/answer there.

What you did?

1. Set PHP version to 8 (I'm using PHP 8.3.3)
2. Create a paste.
3. Try to create a shorten URL from the screen.

What happens

The shorten URL does not created but it doesn't get return to the page and is created to a blank page (you must log into YOURLS to grab the shorten link).

What should happen

Page should refresh with the shorten link like it did when using PHP 7.4

Additional information

Not sure if this is considered a bug or not but creating a support ticket to see if anyone can help me out with this. I am using Plesk panel as well but made sure all settings are in ordered. It works perfectly fine when the PHP version for the privatebin instance is set to 7.4.33. The YOURLS instance is on 8.3.3 and has no issues.

The shorten.php is not anything that this project provides, but I found it mentioned in a discussion of a proposed feature, maybe you were using that?

We have since gained functionality for a YOURLS proxy in #997 which became part of release 1.5. You can find more information on how to set it up in the configuration wiki page as well as in the comments on the relevant settings in the sample configuration file:

PrivateBin/cfg/conf.sample.php

	[yourls]
	; When using YOURLS as a "urlshortener" config item:
	; - By default, "urlshortener" will point to the YOURLS API URL, with or without
	; credentials, and will be visible in public on the PrivateBin web page.
	; Only use this if you allow short URL creation without credentials.
	; - Alternatively, using the parameters in this section ("signature" and
	; "apiurl"), "urlshortener" needs to point to the base URL of your PrivateBin
	; instance with "shortenviayourls?link=" appended. For example:
	; urlshortener = "${basepath}shortenviayourls?link="
	; This URL will in turn call YOURLS on the server side, using the URL from
	; "apiurl" and the "access signature" from the "signature" parameters below.
