TypeError: sourceMapConsumer.eachMapping is not a function with "source-map": "^0.8.0-beta.0"

[Colengms]

Our CI lab upgraded Node to v18 on our CI VM's. That caused us to hit an issue (discussed here: parcel-bundler/parcel#8005 )

The suggested work-around for that issue helped. (to add "source-map": "^0.8.0-beta.0" to the resolutions section).

Unfortunately, this fixed version of source-map appears to break compatibility with vscode-nls-dev. We're now getting:

ERROR in ./src/main.ts
Module build failed (from ./node_modules/vscode-nls-dev/lib/webpack-loader.js):
