Wrong request options in retries

[hahampis]

We are using AsyncAnthropicBedrock class. We noticed that when a request is automatically retried, the request options do not have the correct values, resulting in 400 - Bad request. Example logs (actual content redacted):

This started happening with version 0.31.0. Doesn't happen with version 0.30.1.
Maybe has something to do with #580 ?

Thanks for the report, I can reproduce this, working on a fix.

[RobertCraigie]

this will be fixed in the next release: #585, v0.31.1.

I think this is happening with vertex too.. upon retry you get KeyError: 'model', which I think happens because the options payload is mutated. Fix here: #599

[RobertCraigie]

Sorry about that @yasyf, that will be fixed in the next release: #595

Until it's released (hopefully later today) you can either downgrade or install from github, e.g. python -m pip install -U git+https://github.com/anthropics/anthropic-sdk-python@next.
