Debugging Questions

Hello,

I am trying to help out an open source project that I use. I found an issue and the developer has asked me to help debug the javascript but I'm a javascript hack and not sure how to do it.

The project is coc-tailwindcss
The plugin works in one project but not the other. Here's the issue: https://github.com/iamcco/coc-tailwindcss/issues/22
The developer says the LSP init fail, debug the error at line: https://github.com/iamcco/coc-tailwindcss/blob/master/lsp/tailwindcss-language-server/dist/index.js#L7134
The developer asked me "Use console.log to print info to output channel or follow https://github.com/neoclide/coc.nvim/wiki/Debug-language-server"

I have two questions:
The developer wants the console.log() on 7134. Exactly where in the code should I put it and what variable should I use?
I'm assuming that the output would be in :CocCommand workspace.showOutput but I'm not sure. Am I right? Is there another spot to output?

Best regards.
