Adminer editor runtime PHP error: Cannot access offset of type string on string in /srv/adminer.php:450

[adambisek]

Hello there,
I am experiencing problem below with adminer (4.8.1) while using latest Docker image dockette/adminer:editor

I am opening the bug report here, because I am convinced this is an runtime error somehow caused by the environment, because the same kind of URL works (in same version) Adminer editor demo with dirreferent runtime (https://demo.adminer.org/editor.php?username=&select=songs&where%5B0%5D%5Bcol%5D=album&where%5B0%5D%5Bop%5D=%3D&where%5B0%5D%5Bval%5D=1)
