Community wisdom has long held that good error recovery is impossible for automatically generated parsers and I unquestioningly accepted that wisdom for years. When I was building a Yacc system in Rust, I eventually investigated further, and found that there's loads of work in this area over several decades. None of it ever found its way into real parsers, probably because it was too slow. I extended some of that work a bit, made it more efficient, and took advantage of the speed of modern machines and now have an approach to automatic error recovery that you have to do quite a lot of work to beat with a hand-rolled parser.
