lex-web-ui-loader not loading from baseUrl?

I'm currently trying to upgrade to use version 0.20.6 pre-built libraries. I was previously using 0.19.9.

For some reason now the new loader is not loading "aws-sdk-2.903.0.min.js" from the right location (with the baseUrl pre-appended), also it looks like it's trying to load "lex-web-ui-loader-config.json" even though my loader config specifies to not load from Json file.

The other dependency js/css files are being loaded properly from my baseUrl.

My loader config:
`const loaderConfig = {
baseUrl: 'https://myCDN/0.20.6/',
shouldLoadConfigFromJsonFile: false,
shouldLoadMinDeps: true,
};
`

`const uiConfig = {
ui: { ... },
lex: {...},
};
`

The loading logic:
`const loader = new window.ChatBotUiLoader.FullPageLoader(loaderConfig);
loader.load(uiConfig);
`

Could someone tell me what I'm missing?

Start by reproducing the issue with the 0.20.6 pre-built libraries, the shown baseUrl, and shouldLoadConfigFromJsonFile set to false. Inspect the loader's dependency and configuration-loading entry points to trace the requested URLs; done means aws-sdk-2.903.0.min.js uses the baseUrl and the JSON config is not requested.
