And what /is/ hyprland.conf:356 ?
Are the two lines you posted /in/ your hyprland.conf? Doesn't look like supported syntax at all… https://wiki.hyprland.org/Configuring/Keywords/

I've updated the error line. Please check it and let me know how to fix it.

Please post your entire hyprland config, where did you get that?
Afaik prefixing variables "$" at assignment isn't valid syntax.

On top of that, hyprland cannot really handle random bash syntax in the values, see https://bbs.archlinux.org/viewtopic.php?pid=2240697
