Debugging
Cannot find package 'uuid' imported from /var/task/index.mjs
If your Lambda Layer contains @types/uuid but not the actual uuid package, it means you only have the TypeScript type definitions installed, not the actual library. The @types/uuid package provides type information for TypeScript, but it does not include the actual code for uuid. This is why your Lambda function is throwing an error when it tries to import it.
How to Fix It
You need to make sure that both uuid and @types/uuid are installed in your Lambda Layer.
1. Install uuid
Library
If you haven't already, install the uuid
package along with its type definitions:
npm install uuid @types/uuid
2. Verify the node_modules Structure
Ensure that your node_modules
directory has both the uuid
and @types/uuid
folders:
nodejs/
├── node_modules/
│ ├── uuid/
│ └── @types/
│ └── uuid/
└── package.json
