Starting from this commit and with file-loader 5.0.1 and 5.0.2 (but not 5.0.0) I get the "error" from #212

I don't understand why this happens, but guess it's related to the evaluation of the default value. Unfortunately I don't have any isolated example yet.

When I I explicitly set the option esModule to false it works.

          loader: 'file-loader',
          options: {
            esModule: false,
            ...
          }

Thank you for the quick reply.

Some days ago I updated to "css-loader": "3.4.1" but with the newest release 3.4.2 AND without esModule: false it doesn't work either.

In my concrete case it is an image resource that doesn't work, so file-loader seems to be the relevant loader.

I continued to search for similar problems and found [1]. According to [2] esModule is true by default starting with version 5.0.0.

Could it be, that this (breaking change) didn't work in 5.0.0 and has been fixed with 5.0.1? According to [3] this was just a rename from esModules to esModule.
