crashes due to many uncaught exceptions in hyprland module

[2024-06-28 13:25:12.496] [error] Hyprland IPC: Couldn't write (4)
terminate called after throwing an instance of 'std::runtime_error'
  what():  Error parsing JSON: * Line 1, Column 1
  Syntax error: value, object or array expected.

[1]    2547530 IOT instruction (core dumped)  waybar

Seems an empty string is returned to caller here but the caller expects a valid JSON string:

Waybar/src/modules/hyprland/backend.cpp

Line 199 in ccc3c13

return "";

which then fails to parse as JSON.

the vast majority of calls to getSocket1Reply or getSocket1JsonReply ought to be wrapped in try/catch, i don't think this is really a fatal class of error, I get crashes constantly when load is high. maybe an option to increase the socket timeout would alleviate the issue?

Could you try #3389
