Looking at the mentioned question, it seems a NULL pointer arrives as first argument in phutil_encode_log(). Fortunately that function is used by only 3 places:

@jeanguyomarch: If you could provide stacktraces of these issues, that would be awesome.

On it, thank you!

My friend, I think you are affected by this change, and this applies to whatever PHP version

I'm on the latest pull, commit f81e821abf2b275d1778d02a018a4d0af7208be8.
A bit off topic here :) but I'll quickly sum up the issue I'm having (and am in the middle of trying things to fix):

• Visiting https://[phorge instance]/auth/config/view/2/, where my Github auth item is, makes nginx dump a blank 502 page, no further info.
• First instinct is to check the /var/log/nginx/error.log, where I get a PHP stack trace concatenated into one line, and an nginx header length error (reformatted for readability. the PHP error is truncated):

Oh, totally possible that I forgot to update it :)

I'll take your word on it that it's supported, though the current installation guide says otherwise.
Further, I had a few roadbumps on a fresh install to a new server with PHP 8, that I suspect may relate to strlen(NULL) behavior, but I did need to set up PHP 7 to make sure that was or wasn't the case.
(I'm in the process of reproducing those and working out a possible cause or trace. Some manifested as warning banners, one as a 502 on my end in the GitHub auth provider.)

We already support PHP 8...
