My first surprise on it:

I made an error trying with aws bedrock where I used "bedrock" instead of "bedrock-runtime".

The native library will give you an error back.

Langchain didn't try and do anything, just kept parsing the json and gave me a KeyError.

I was able to get a small fix, but was surprised they have no error like ConfigurationError that goes across all their backends at all.

The best I could get them to add was ValueError and worked with the devs to make the text somewhat useful.

But was pretty surprised, I'd expect a badly configured endpoint to be the kind of thing that happens when setting stuff up for the first time, relatively often.
