request failed is not an error message its a shrug

The pattern I like is that every error carries the field that failed and the value it actually received. It costs the library author about ten minutes and saves every user an afternoon. It is probably the highest leverage thing in a client library and it is almost always the last thing anyone gets round to.

对对对 就要这种 😂 我现在选库先翻 issue 区看别人的报错长什么样 比看文档快多了 ✨
