How to get null-ls to automatically mount to file types

[irishgreencitrus]

Hey, apologies if this is already a question, however I have looked around and there seems to be no sources with my specific problem.

The problem is that null-ls detects all the formatters and linters yet fails to mount to the correct file type.
Is this something on mason's end or should I be looking around configuring null-ls

Any help appreciated

you have to explicitly configure each formatter/linters
for example: to setup clang_format

require("null-ls").setup({
    sources = {
        require("null-ls").builtins.formatting.clang_format.with({
            command = "clang-format",
            args = {
                "-assume-filename",
                "$FILENAME",
            },
            to_stdin = true,
        })
    },
})
