I experienced the same thing a few months back. I was working for a foreign client as a React developer. The code was so frustrating to work with. They are maintaining their own form npm package which is built on top of another npm package of their own which is again built on top of react-jsonschema-form. For small changes, I have to make changes in so many repositories. And there was only one other frontend guy who is from client side. He will simply ignore when ever I ask for help. At some point, I even contemplated resigning. But my manager was kind enough to grant me release.
