How to use `Lua.format.defaultConfig`?

[FalcoGer]

I have read the documentation for it here, but it doesn't seem to do anything. On top of that, coc gives me lots of diagnostics about wrong types, wanting anything that isn't a string to be a string.

If I make everything a string it still doesn't work.

Here is my config. When I call coc's format action, the indents don't change to 2 wide, for instance and instead go to the default of 4.
