What’s the problem? Minification!
However, minification of already minified client libraries is not that straightforward and is apparently a build breaker 😲.
What’s the solution? Clientlib Preprocessor!
After a day or two, I remembered I worked on Client library preprocessing at a previous project. For each client library you can define what preprocessor to use for minification. One of the valid values is
none, so no minification. After configuring the clientlib to not minify it, the build was again successful.
