Issue
Partially fixes #114, where the
cos_agent
charm library is not compatible with charms or other charm libraries that use Pydantic v2.Solution
Pydantic v2 provides full v1 compatibility via the
pydantic.v1
namespace. When it is detected that the environment is using Pydantic v2, switch to using that instead of importing Pydantic v2.Upgrade Notes
This should have no impact on any existing charms.
