In this case, filetype is only set after null-ls initialized, you have to manually start the sources.

I consider this not an issue? I'm open to discussing.

I don't know when and how null-ls initialized, but lsp server is started after set filetype.

PS: If null-ls's sources could be attached manually, please tell me, thx.

You could could force it to start by starting the buffer with a file name, even if it does not exist yet
