Mongoose 6.6.6 fails to build browser.umd.js file and the released module contains build result from 5.13.15

[maciasello]

Prerequisites

• I have written a descriptive issue title
• I have searched existing issues to ensure the bug has not already been reported

Mongoose version

6.6.6

Node.js version

18.7.0

MongoDB server version

Typescript version (if applicable)

Description

npm run build-browser fails on the current master. Even then it reports Browser build successful.. Despite that the published package contains dist/browser.umd.js, which is equal to the one built (successfully) from 5.x branch.

Steps to Reproduce

Failing build:

$ git switch master
$ git clean -f -x .
$ npm i
$ npm run build-browser

> mongoose@6.6.6 build-browser
> node ./scripts/build-browser.js

Starting browser build...

Browser build successful.

Identical browser.umd.js files:

$ wget -O mongoose-6.6.6-browser.umd.js https://unpkg.com/mongoose@6.6.6/dist/browser.umd.js
$ wget -O mongoose-5.13.15-browser.umd.js https://unpkg.com/mongoose@5.13.15/dist/browser.umd.js
$ diff mongoose-5.13.15-browser.umd.js mongoose-6.6.6-browser.umd.js
<empty output means no diff>

Also verified on the local build on 5.x branch.

Expected Behavior

dist/browser.umd.js on branch 6.6.6 builds and contains relevant content.

I can confirm that build 6.6.5 also contains 5.13.15's dist/browser.umd.js file (checked because it is the last release mentioned on GH).

I'm so sorry for this issue. We will fix this and ship 6.6.7 today.

[maciasello]

@vkarpov15 No worries! Please verify if fixing that doesn't close gh-12392 in one shot.
