app.overlay parse error: expected '{', '=', or ';'

Question

Getting the'{', '=', or ';' error during generate and build...

Checked the attached file for hidden characters in both notepad and vscode editors.

5100.app.overlay

Can someone recommend what might be tripping this up?

here is the .overlay text:

/ {

camera_bus: camera_bus {

compatible = "perioprobe,hm01b0-parallel";

pclk-gpios = <&gpio1 14 GPIO_ACTIVE_HIGH>;

vsync-gpios = <&gpio2 10 GPIO_ACTIVE_HIGH>;

lvld-gpios = <&gpio0 3 GPIO_ACTIVE_HIGH>;

d0-gpios = <&gpio2 8 GPIO_ACTIVE_HIGH>;

d1-gpios = <&gpio2 6 GPIO_ACTIVE_HIGH>;

d2-gpios = <&gpio2 5 GPIO_ACTIVE_HIGH>;

d3-gpios = <&gpio2 4 GPIO_ACTIVE_HIGH>;

reset-gpios = <&gpio2 9 GPIO_ACTIVE_LOW>;

};

The errors:
