Floorplan SVG's not blending when clicked

Hello all,

I’m trying to make a floorplan of my home using the ha-floorplan. I have followed some tutorials online but can’t seem to get it right. I can see the floorplan in my dashboard and when I click it, the lights go on but the dashboard doesn’t change (SVG’s should blend).
For simplicity I’ve only added 2 SVG’s and 1 light.
This is my config.yaml:

            views:
              - title: Floorplan
                path: floorplan
                icon: 'mdi:floor-plan'
                theme: lovelace-blue-blur
                panel: true
                cards:
                - type: 'custom:floorplan-card'
                  style: >
                    ha-card {
                      max-width: 150vh;
                      margin: 0 auto;
                      background: none;
                    }
                  config:
                    image: http://my_ip:8123/local/community/flooraplan_test2/floorplan_opt.svg
                    stylesheet: http://my_ip:8123/local/community/floorplanner_home.css
                    rules:
                      - entities:
                        - light.woonkamer
                        tap_action:
                          action: 'toggle'
                        state_action:
                          action: call-service
                          service: floorplan.style_set
                          service_data:
                            element: "${entity.entity_id.replace('light.', 'light_overlay.')}"
                            style: |
                              >
                              if( entity.state !== "on" )
                                return "display: none;";
                              let hue = 0;
                              let sat = 0;
                              if( entity.attributes.hs_color )
                              {
                                hue = entity.attributes.hs_color[0];
                                sat = entity.attributes.hs_color[1];
                              }
            
                              if(sat < 10)
                              {
                                return '
                                  display: block;
                                  filter:
                                    brightness(calc( ${entity.attributes.brightness} / 255));'
                              }
                              return '
                                display: block;
                                filter:
                                  sepia(100%)
                                  hue-rotate(calc( ${hue}deg-55deg))
                                  saturate(calc( ${sat}%*2))
                                  brightness(calc( ${entity.attributes.brightness}/255));
                              '

My CSS code:

          svg, svg * {
            pointer-events: all !important;
            cursor: auto !important;
          }
          
          #light-overlays image {
            display: none;
            mix-blend-mode: lighten;
          }
          
          #light-overlays image.light-on {
            display: block;
          }
          
          #areas path {
            stroke: transparent;
            stroke-width: 0;
          } 

I’ve created my SVG with Inkscape resulting in this optimized SVG:

        <?xml version="1.0" encoding="UTF-8"?>
        <svg width="1920mm" height="1080mm" version="1.1" viewBox="0 0 1920 1080" xml:space="preserve" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"><g id="background"><image id="main-background" width="1920" height="1080" preserveAspectRatio="none" xlink:href="http://192.168.68.58:8123/local/community/flooraplan_test2/floorplan0000.png"/><g id="light-overlays"><image id="light_overlay.woonkamer" width="1920" height="1080" preserveAspectRatio="none" xlink:href="http://192.168.68.58:8123/local/community/flooraplan_test2/floorplan0008.png"/></g></g><g id="areas"><g id="area.woonkamer"><path id="path1" d="m18.048 346.93 232.62-254.68 1620.4 411.1-226.61 491.32-1628.4-413.11z" fill="none" stroke="#000"/><use id="light.woonkamer" xlink:href="#path1"/></g></g></svg>

When I inspect my dashboard, I get an error but I don’t know what it means:

    floorplan.js?hacstag=1883234941043:131 SyntaxError: Unterminated string constant (13:9) (at floorplan.js?hacstag=1883234941043:16:104348)

This is what I can see:

Does anybody see what I’m doing wrong?
Thanks in advance!
