Default deploy installs eoapi-cdk 10.3.0, whose STAC runtime fails to import (`No module named 'stac_fastapi.extensions.core.fields'`)

Description

Deploying eoapi-template from a fresh clone produced a STAC API that returned 500 Internal Server Error on every request. The cause seemed to be dependency resolution: pyproject.toml specifies eoapi-cdk>=10.3.0,<12, and a fresh uv sync resolves to the lower bound, 10.3.0. The STAC API runtime bundled by eoapi-cdk 10.3.0 raises an ImportModuleError at Lambda handler import. Upgrading eoapi-cdk to 11.6.0 resolved it for me.

Environment:

• Fresh clone of eoapi-template, deployed to AWS (us-west-2)
• uv sync resolved eoapi-cdk==10.3.0 (confirmed in uv.lock)
• Python 3.14.2, Node v24.13.0, deployed via npx cdk deploy --all

What happened:

Once deployed, I attempted to hit the STAC API endpoint:

Looking in the CloudWatch logs I noticed:

Forcing eoapi-cdk to the latest version resolved it. Upon redeploying, I was able to hit the endpoint:
