Config doesn't compile when sensors are added

[aDogCalledSpot]

I'm currently working on my configuration for my Swoop which features optional EC11 rotary encoders on both halves of the split keyboard. I've added the encoder on the left, but not on the right.

You can see my full configuration here.

The most relevant part (I think) is in the swoop.dtsi:

    kscan0: kscan {
        compatible = "zmk,kscan-gpio-matrix";

        diode-direction = "col2row";
        row-gpios
            = <&pro_micro 4 (GPIO_ACTIVE_HIGH | GPIO_PULL_DOWN)>
            , <&pro_micro 5 (GPIO_ACTIVE_HIGH | GPIO_PULL_DOWN)>
            , <&pro_micro 6 (GPIO_ACTIVE_HIGH | GPIO_PULL_DOWN)>
            , <&pro_micro 7 (GPIO_ACTIVE_HIGH | GPIO_PULL_DOWN)>
            ;
    };

	left_encoder: encoder_left {
		compatible = "alps,ec11";
        a-gpios = <&pro_micro 8 (GPIO_PULL_UP | GPIO_ACTIVE_HIGH)>;
        b-gpios = <&pro_micro 9 (GPIO_PULL_UP | GPIO_ACTIVE_HIGH)>;
        resolution = <4>;
        status = "disabled";
	};

	right_encoder: encoder_right {
		compatible = "alps,ec11";
        a-gpios = <&pro_micro 9 (GPIO_PULL_UP | GPIO_ACTIVE_HIGH)>;
        b-gpios = <&pro_micro 8 (GPIO_PULL_UP | GPIO_ACTIVE_HIGH)>;
        resolution = <4>;
        status = "disabled";
	};

/*
    sensors: sensors {
        compatible = "zmk,keymap_sensors";
        sensors = <&left_encoder &right_encoder>;
        triggers-per-rotation = <20>;
    };
*/

With the sensors commented out (as above) everything compiles fine but when I try to uncomment the lines I receive the following failure:

In my swoop.conf I added the following lines:

CONFIG_EC11=y
CONFIG_EC11_TRIGGER_GLOBAL_THREAD=y

To me it looks as if I'm missing a config setting but I wasn't able to find the right one in the docs.

Any help is appreciated.
