Issue with uv sync for A2A sample app

[jaycoolslm]

I've set up my local directory as per the Google blogpost

mkdir sdk
git clone https://github.com/Universal-Commerce-Protocol/python-sdk.git sdk/python
pushd sdk/python
uv sync
popd
git clone https://github.com/Universal-Commerce-Protocol/samples.git
cd samples/rest/python/server
uv sync

Rest server demo works fine.

However, when I try to run the A2A demo I get this error at the uv sync stage

It looks like it's related to the uv.lock.

As per Claude Code: The issue is clear: your uv.lock file contains URLs for a private Google Artifact Registry that requires authentication. This lock file was likely generated on a different machine with access to that registry.

This fixed it: rm samples/a2a/business_agent/uv.lock && uv sync
