DEP_WEBPACK_DEPRECATION_ARRAY_TO_SET warning

[gilvex]

When I use ncc build it throws me this warnings

(node:13680) [DEP_WEBPACK_DEPRECATION_ARRAY_TO_SET] DeprecationWarning: Compilation.modules was changed from Array to Set (using Array method 'reduce' is deprecated)
(Use 'discord-basebot-core --trace-deprecation ...' to show where the warning was created)        
(node:13680) [DEP_WEBPACK_MODULE_ERRORS] DeprecationWarning: Module.errors was removed (use getErrors instead)

How to disable this warning?

Which version of ncc are you using and can you provide the code you're trying to compile?

Which version of ncc are you using and can you provide the code you're trying to compile?

Version is 0.28.3

the code

export default () => {}

I'm trying to programmatically compile it like this

const { code }: { code: string } = await ncc( path.join(process.cwd(), entryFiles[0]), {
            minify: true,
            quiet: true
        })

The issue didn't resolved :( How to deal with this? (How to ignore or handle maybe?)

(node:18244) [DEP_WEBPACK_DEPRECATION_ARRAY_TO_SET] DeprecationWarning: Compilation.modules was changed from Array to Set (using Array method 'reduce' is deprecated)

(node:18244) [DEP_WEBPACK_COMPILATION_ASSETS] DeprecationWarning: Compilation.assets will be frozen in future, all modifications are deprecated.
BREAKING CHANGE: No more changes should happen to Compilation.assets after sealing the Compilation.
        Do changes to assets earlier, e. g. in Compilation.hooks.processAssets.
        Make sure to select an appropriate stage from Compilation.PROCESS_ASSETS_STAGE_*.

const ncc = await require('@vercel/ncc')(`${process.cwd()}/${tsFilePath}`, {
        quiet: true
    })

Looks like the warning is coming from ts-loader
