all webcomponents files should be named as follow:
---.dockmanager.config.json
---.licensed.config.json
---.oss.config.json
because there is a webpack config that looks for ---.config files when building

new CopyPlugin({
            patterns: [
                {
                    context: path.resolve(__dirname),
                    from: "*config.json",
                    to: path.resolve(__dirname, "dist"),
                },
            ],
        }),

Currently, the tree webcomponents configs are not coppied in the dist folder when built.

Also, I have an error when trying to build the angular docs:

It seems to be something around the reading of the produced filePath:

    const config = JSON.parse(fs.readFileSync(filePath, 'utf8'));
