actions: option bad indentation issue

[damiano75]

Hi,
when I add the actions: option in the popup card I have an error message about bad indentation from the previous line.
In the code below the bad indentation error starts at "settings:true" line, if I remove the actions: section there isn't any error.
Could please help me to find where I'm wrong?

    popup_cards:
      light.striscia_led:
        title: My popup
        style:
          $: |
            .mdc-dialog .mdc-dialog__container {
              width: 50%;
            }
            .mdc-dialog .mdc-dialog__container .mdc-dialog__surface {
              width:50%;
              box-shadow:none;
            }
          .: |
            :host {
              --mdc-theme-surface: rgba(0,0,0,0);
              --secondary-background-color: rgba(0,0,0,0);
              --ha-card-background: rgba(0,0,0,0);
              --mdc-dialog-scrim-color: rgba(0,0,0,0.8);
              --mdc-dialog-min-height: 70%;
              --mdc-dialog-min-width: 70%;

            }

              color: "#FDCA64"
              name: Relax

The error:

YAML needs a space between "action:" and "call-service". Now it works

@DBuit would be good to update the readme example with this fix!
