In the errorlog of my webservice, I see a line
2019-12-03 16:05:07: (mod_fastcgi.c.2543) FastCGI-stderr: PHP Warning: include(): Failed opening 'doSearch1.inc.php' for inclusion (include_path='.:/usr/share/php') in /data/project/...
Webservice is started with "webservice --backend=kubernetes php7.2 start"
Note that /usr/share/php there is no such directory, there is a lot of /usr/share/php7.2-<something> and a few /usr/share/php7.0-<something>
So you may consider to remove /usr/share/php from the path, or replace it somehow.
