v3 migration issue

[dkraklan]

My configuration for rest-nvim has been unchanged for months but after updating to the latest version it breaks my configuration and I get the following error.

Failed to run `config` for rest.nvim

.../.local/share/nvim/lazy/rest.nvim/lua/rest-nvim/init.lua:19: Couldn't convert lua value

# stacktrace:

Configuration is below, looking at the readme it seems the way to configure rest-nvim may have changed, although I'm not sure how to convert what I have to the new method as it doesn't seem to have the same options. I'm also not familiar with using vim.g to configure a module. Is the old method of configuration no longer supported?
