Hey @strong spade apologies about the disruption here! You'll need to pin cartesia-line==0.1.12 in your agent's pyproject.toml and re-deploy.

We recently released v0.2.0 of the SDK, which introduces breaking changes. If your project doesn't pin the SDK version then you may be unknowingly getting upgraded to the latest version.

#
