misleading error message when remoteEntry.files is empty

[kbrooks]

Describe the bug

When building my mfe I ran into the following error

HookWebpackError: [ Module Federation Manifest Plugin ]: remoteEntry chunk should not have multiple files!, current files:
    at makeWebpackError (/Users/kyle.brooks/.../node_modules/.pnpm/[email protected]/node_modules/webpack/lib/HookWebpackError.js:48:9)

The message is misleading because files is actually an empty set.

Reproduction

i already fixed the problem in a pr

Used Package Manager

pnpm
