Problem with nested modifiers

[b-m-f]

This is a part of my config

        tri_layer {
        bindings = <
        &kp LC(LA(LS(LEFT))) &kp LC(LA(LS(RIGHT))) &kp LG(PAGE_UP) &kp LG(PAGE_DOWN) &bt BT_CLR   &kp LA(H) &kp LA(J) &kp LA(K) &kp LA(L) &kp LA(MINUS)
        &trans &trans   &trans   &trans  &trans                                                   &kp LEFT &kp DOWN &kp UP &kp RIGHT &kp LA(BACKSLASH)
        &kp LG(UP) &kp LG(LEFT) &kp LG(RIGHT) &trans &trans                                       &kp K_COPY &kp K_PASTE &kp K_VOL_DN &kp K_VOL_UP &kp PRINTSCREEN
        &trans &trans                                                                             &trans &trans
        >;
        };

The parens on the first row lead to the following error:

zmk-config (master) $ zmk-viewer generate splitkb/aurora/sweep/rev1 -r -f config/splitkb_aurora_sweep.keymap

The generated png is simply the empty keymap
