2 years ago Hello, I just confirm I have same problem with Nagvis 1.9.32 (night buid from 26.4.2022) and PHP 8.1.5
NagVis website http://ip.ad.re.ss/nagvis/ says:
_Error: (0) preg_match(): Passing null to parameter #2 ($subject) of type string is deprecated URL: /nagvis/frontend/nagvis-js/index.php File: /usr/lib/nagvis/share/frontend/nagvis-js/ext/dwoo-1.1.0/Dwoo/Compiler.php Line: 1695

hope it helps someone to fix it ;) thank you Pep.
BTW: downgrading to Nagvis 1.9.28 does not work here
Hi,
Yesterday we tried to update our NagVis from 1.9.28 to 1.9.30. After update we get the following error immediately after NagVis website login:
Error: (0) preg_match(): Passing null to parameter #2 ($subject) of type string is deprecated URL: /nagvis/frontend/nagvis-js/index.php File: /nagios/nagvis/nagvis/share/frontend/nagvis-js/ext/dwoo-1.1.0/Dwoo/Compiler.php Line: 1695
0 [internal function]: nagvisExceptionErrorHandler(8192, 'preg_match(): P...', '/nagios/nagvis/...', 1695)
1 /nagios/nagvis/nagvis/share/frontend/nagvis-js/ext/dwoo-1.1.0/Dwoo/Compiler.php(1695): preg_match('#^(['"]).*?\1$#', NULL)
2 /nagios/nagvis/nagvis/share/frontend/nagvis-js/ext/dwoo-1.1.0/Dwoo/Compiler.php(1302): Dwoo_Compiler->parseFunction('
I guess "preg_match" is deprecated in PHP 8.1...
Temporary solution was: rollback NagVis update to 1.9.28
Today we downgraded PHP 8.1.4 to 8.0.17. NagVis 1.9.28 still works, later today or tomorrow we will try to update Nagvis to 1.9.30 once again...
OS: Linux iuaw155 3.10.0-1160.59.1.el7.x86_64 #1 SMP Wed Feb 16 12:17:35 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
Is there any plan to have latest Nagvis compatible with PHP 8.1.x?
Thanks!
Taki
