error decoding response body when resolving dependencies from aws codeartifact repo since 0.5.12

[okan-agca-entrix]

Hello,
I'm encountering a new error since upgrading to 0.5.12 while running uv sync. The setup is described below. The error is not present with version 0.5.11 of uv. If there are migration steps I missed, would be happy if you can direct me there. Had a brief look at the release notes but didn't see anything relevant.

Error Message from Github Actions:

Setup:
The code artifact url is setup in the pyproject toml

name = "aws-code"
url = "https://***-***.d.codeartifact.eu-west-1.amazonaws.com/pypi/***/simple/"

The credentials are setup as environment variables as documented here: https://docs.astral.sh/uv/guides/integration/alternative-indexes/#aws-codeartifact

I can confirm same error occurs with Azure Artifacts. With v0.5.11 dependencies from our private Azure Artifacts library were installed by uv. Now, with v0.5.12 I get the same error as @okan-agca-entrix .

Can verify the error

Error happens with Gitlab package registry:

Sorry -- this is a bug in reqwests that I fixed last night (#10187), but didn't realize that the subsequent release failed. I'll get it out now.

[olafdeleeuw]

No problem. Thanks!

[charliermarsh]

This should be fixed in v0.5.13.

If you're on v0.5.12, you may need to reinstall with cURL rather than via uv self update:

curl -LsSf https://astral.sh/uv/install.sh | sh

Sorry for the inconvenience! It's my mistake for going to bed without double-checking the release pipeline.

[thiago-pythonic]

Thanks for the quick turnaround! 0.5.13 works just fine!

[olafdeleeuw]

Thanks! Also with Azure Artifacts. Everything works fine again with 0.5.13.

out of interest is there any way you can maintain previous versions in homebrew just in case there is a problem like this again? This caused us a bit of havoc because brew doesn't maintain any old versions

[charliermarsh]

Hmm, I think that's ultimately up to Homebrew, since I didn't do anything specific to have it not publish to Homebrew. It's possible that the releases were just too close together, and so Homebrew never built and uploaded 0.5.12?
