4 Silent Failures, 2 Undocumented APIs, and a Container That Crashed Because of a Missing User Directive

Short summary

A developer documents a week-long debugging saga deploying a CrewAI agent to AWS Bedrock AgentCore, encountering four silent failures: a fake PyPI package, 200 OK responses masking IAM permission gaps, container crashes from a missing USER 1000 Dockerfile directive, and undocumented naming regex constraints. Each failure required reading source code with zero error signals. The post includes concrete fixes and Dockerfile corrections for each issue.

• •AWS Bedrock AgentCore SDK is on CodeArtifact, not PyPI — the PyPI package is a placeholder trap
• •Missing IAM permissions return HTTP 200 with empty payload instead of an error
• •AgentCore containers must run as UID 1000 or they crash silently with no logs
