The loadConfigFromBundledFile function patches the default require algorithm for the fileName file. It replaces the require.extensions handler for it. In certain scenarios the file name parameter value in the require.extensions handler differs from the required file name (for example for symlinked files). The #3783 fix processed this by preparing the input file name before comparation. It uses the fsPromises.realpath function for it. The problem is that the fsPromises.realpath result and the file name in the require.extensions handler are not the same in certain scenarios (refer to the relevant issue list above). I suggest use the require.resolve function instead of the fsPromises.realpath because the require and the require.resolve functions use the same algorithm.
