"remoteEntry chunk should not have multiple files!, current files:" because ZERO files. SOLVED

[JasonKleban]

Even for "@module-federation/node": "2.2.6", I'm getting "remoteEntry chunk should not have multiple files!, current files:" with zero files.

core/packages/manifest/src/StatsManager.ts

Line 91 in 9799d2c

`remoteEntry chunk should not have multiple files!, current files: ${files.join(

remoteEntryNameChunk.files is an empty set/array as confirmed by debugging. But I don't know what could lead to this unexpected situation?

When I comment out the failing assertion and give some fallback values, I get a different helpful error that the name parameter that I supply to new UniversalFederationPlugin({ name: 'not-a-valid-js-identifier' )

Library name base (not-a-valid-js-identifier) must be a valid identifier when using a var declaring library type.

When I fix this problem, the original issue disappears.
