Error: EACCES: permission denied on uhk-agent launch #2679
Description
While testing uhk-agent on NixOS, I saw this issue on startup where a directory is being created, however, the parent directory is not writable. The GUI is not visible, and the application hangs on the last line of the log:

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 2)
This issue can be worked around by manually setting the permissions on the parent directory, and creating the doc-dev dir:
chmod +w ~/.config/uhk-agent/smart-macro-docs/UltimateHackingKeyboard/firmware/v14.0.0
mkdir ~/.config/uhk-agent/smart-macro-docs/UltimateHackingKeyboard/firmware/v14.0.0/doc-dev
However, maybe there is a deeper issue here? Why would the parent directory be set to not writable?
