I have a problem with EsLintWebpackPlugin. Once it is included in my project, it outputs a weird browser warning:

I used this plugin; below is the code snippet:
plugins: [
...
new ESLintPlugin({
failOnError: true,
failOnWarning: false,
context: `${process.cwd()}/src`,
})
]
I have set up the ESLint rules, and changing them did not affect the output of the warning. It seems to me this is coming from the plugin, but I do not know what is happening.
Any help will be appreciated, thanks!
