Root Cause

AWS Lambda deployment package exceeds 250MB unzipped limit.

generic

Workarounds

  1. 88% success Use Lambda layers to separate dependencies from code 
    aws lambda publish-layer-version --layer-name deps --zip-file fileb://layer.zip
  2. 92% success Use container image deployment (up to 10GB) 
    Package as Docker image and deploy via ECR

Dead Ends

Common approaches that don't work:

  1. Compress the deployment package more aggressively 88% fail

    The 250MB limit applies to unzipped size, not zip size.

  2. Split into multiple Lambda functions with shared code 65% fail

    Each function still needs its own dependencies bundled.
