Webpack warning: 'Map' was not found in 'bson'

I use ejson-shell-parser : 1.2.2 together with bson : 5.0.1 (aka the latest versions at the time of writing this issue). When I bundle my application with Webpack, I do get the following warning:

WARNING in ./node_modules/ejson-shell-parser/dist/ejson-shell-parser.esm.js 177:25-33
export 'Map' (imported as 'bson') was not found in 'bson' (possible exports: BSON, BSONError, BSONRegExp, BSONRuntimeError, BSONSymbol, BSONType, BSONValue, BSONVersionError, Binary, Code, DBRef, Decimal128, Double, EJSON, Int32, Long, MaxKey, MinKey, ObjectId, Timestamp, UUID, calculateObjectSize, deserialize, deserializeStream, serialize, serializeWithBufferAndIndex, setInternalBufferSize)

The export of Map from bson has been removed in the release 5.0.0 (see NODE-4712 in the release notes).

esjson-shell-parser is supposed to be compatible with bson 5 since the release 1.2.1 (see this PR). Unfortunately, this change seems to be the one triggering a warning during the Webpack build.

The only workaround I found so far is to fallback to the CommonJS version using Webpack Resolve:

config.resolve.alias = {
  'ejson-shell-parser': path.join(ROOT_DIR, 'node_modules', 'ejson-shell-parser', 'dist', 'ejson-shell-parser.cjs.js'),
};
