For more context:

• here's the pull request (though I'll likely be reverting to a prior plugin)
• the failed build
• the repo at the given state

I added some debugging output within the ESLint file.

function isFilePath(nameOrPath) {
  console.log({nameOrPath});
    return (
        /^\.{1,2}[/\\]/u.test(nameOrPath) ||
        path.isAbsolute(nameOrPath)
    );
}

Just before the failure, I get:

{
  nameOrPath: ESLintWebpackPlugin {
    key: 'ESLintWebpackPlugin',
    options: {
      extensions: [Array],
      emitError: true,
      emitWarning: true,
      failOnError: true
    },
    run: [Function: bound run] AsyncFunction
  }
}

So, my current understanding, is that ESLint is not meant to consume objects within the plugins configuration.

Did I misconfigure something, or is this a proper bug?

Though not the final answer, it at least provided a next step. To future engineers, please read any further comments in this discussion, or more likely, review the submitted Issue.

Therefor, I'll mark this response as the answer, since it at least addresses next steps.

Turns out, I mis-configured my application.
