[Bug] Cannot compile preonic/rev3_drop on LAYOUT_preonic_1x2uC

[xmjaj]

It seems that I cannot successfully bake a new firmware using LAYOUT_preonic_1x2uC. QMK configurator gives out this error message:

☒ Invalid JSON keymap: /qmk_compiler/qmk_firmware/preonic-rev3_drop-preonic-3.json : 'LAYOUT_preonic_1x2uC' is not valid under any of the given schemas

I uploaded a .json file that I was able to compile a few weeks back and wanted to add a few keys to one of my layers. But after compiling, I get the error message above. Here is the .json file contents:

A fix (#16520) has been merged for this. It might take some time for it to reach Configurator, but I've tested your keymap and it builds fine locally now.
