Error "Integer expression expected."

Hi, i have installed waybar-updates via AUR, but when I call the script I get the following output: `~ $ waybar-updates /usr/bin/waybar-updates: Zeile 185: [: : Ganzzahliger Ausdruck erwartet. /usr/bin/waybar-updates: Zeile 185: [: : Ganzzahliger Ausdruck erwartet. {"text":"6","alt":"pending-updates","tooltip":"\t\t \t  5\t  1\n\nhyprland 0.47.0-2 -> 0.47.1-1\nperl-image-exiftool 13.16-1 -> 13.17-1\npython-executing 2.1.0-2 -> 2.2.0-1\npython-prompt_toolkit 3.0.48-2 -> 3.0.50-1\nsdl2-compat 2.30.50-2 -> 2.30.51-1\nideamaker 5.1.4-1 -> 5.1.4-2","class":"pending-updates"} ` I have temporarily fixed it by commenting out line 135.
