Quick Statements instance installed as part of Wkibase "bundle" docker image is only partly functional.
It allows adding data with "New batch" functionality. All "user-related" functionality, e.g. "Last batches" do not work.
Apparently the software reports issues with accessing database (surfacing as an error trying to read credentials, but the underlying database tables are also not present in provided images).
parse_ini_file(/data/project/root/replica.my.cnf): failed to open stream: No such file or directory in /var/www/html/magnustools/public_html/php/ToolforgeCommon.php on line 162
The issue is likely stemming from the fact that Quick Statements have been created in the WMF Tool Labs environment, and they're not fully ready to be used outside of it.
