What is the “Cannot find package ‘aws-sdk’ imported from /var/task/index.mjs” Error?
This error typically occurs when your AWS Lambda function is unable to find the ‘aws-sdk’ package, which is essential for interacting with AWS services. The error message usually looks like this:
Error: Cannot find package 'aws-sdk' imported from /var/task/index.mjs
at loadModule (/var/task/index.mjs:5:15)This error can manifest in different ways, depending on your project setup and the environment you’re running in. But don’t worry, we’ll cover the most common scenarios and solutions to get you out of this pickle.
Cause 1: Missing or Invalid ‘aws-sdk’ Installation
The first and most obvious cause of this error is a missing or invalid installation of the ‘aws-sdk’ package. This can happen if you forgot to install the package or if the installation process went awry.
Solution:
Check if you have installed the ‘aws-sdk’ package correctly by running the following command in your terminal:
npm ls aws-sdkIf the package is not installed, run the following command to install it:
npm install aws-sdkIf you’re using yarn, you can install it with:
yarn add aws-sdkCause 2: Incompatible Node.js Version
The ‘aws-sdk’ package has specific requirements for Node.js versions. If you’re running an incompatible version, you’ll encounter this error.
Solution:
Check your Node.js version by running:
node -vEnsure you’re running a compatible version of Node.js (at least 14.17.0) by upgrading or downgrading accordingly.
Cause 3: AWS Lambda Function Handler Issues
Sometimes, the error can occur due to issues with your AWS Lambda function handler.
Solution:
Check your Lambda function handler code to ensure it’s correctly importing the ‘aws-sdk’ package. Make sure you’re using the correct import statement:
import * as AWS from 'aws-sdk';Verify that your handler code is correctly configured and that you’ve specified the correct handler in your AWS Lambda function settings.
Cause 4: Package Lock File Issues
Corrupted or outdated package lock files can also lead to this error.
Solution:
Delete your package lock file (package-lock.json or yarn.lock) and run:
npm installor
yarn installThis will recreate the package lock file and ensure all dependencies are installed correctly.
Cause 5: AWS Lambda Layer Issues
If you’re using AWS Lambda layers, outdated or incorrect layer configurations can cause this error.
Solution:
Verify that your Lambda layer configuration is correct and up-to-date. Check the layer ARN and ensure it’s correctly specified in your AWS Lambda function settings.
Cause 6: File System Issues
In rare cases, file system issues can prevent the ‘aws-sdk’ package from being found.
Solution:
Check your file system for issues and ensure that the ‘node_modules’ directory is present and correct. Try deleting the ‘node_modules’ directory and running:
npm installor
yarn installThis will reinstall all dependencies, including the ‘aws-sdk’ package.
Troubleshooting Steps
If none of the above solutions work, try the following troubleshooting steps:
- Verify that your AWS Lambda function settings are correct, including the handler, runtime, and environment variables.
- Check the AWS CloudWatch logs for any error messages that might indicate the root cause of the issue.
- Test your code locally using a local Node.js environment to isolate the issue.
- Try deploying a minimalistic AWS Lambda function with the ‘aws-sdk’ package to isolate the issue.
Conclusion
The “Cannot find package ‘aws-sdk’ imported from /var/task/index.mjs” error can be frustrating, but by following this guide, you should be able to identify and solve the underlying cause. Remember to check your package installation, Node.js version, AWS Lambda function handler, package lock file, AWS Lambda layer configuration, and file system for any issues.
By methodically working through these potential causes and solutions, you’ll be able to resolve the error and get your AWS project back on track. Happy coding!

Frequently Asked Question
Don’t let the “Cannot find package ‘aws-sdk’ imported from /var/task/index.mjs” error hold you back! Get answers to the most pressing questions below.
What causes the “Cannot find package ‘aws-sdk’ imported from /var/task/index.mjs” error?
This error usually occurs when the AWS SDK package is not installed or not correctly linked in your Lambda function. Make sure you’ve installed the required package using npm or yarn, and also ensure that the package is correctly imported in your Lambda function code.
How do I install the AWS SDK package in my Lambda function?
You can install the AWS SDK package using npm by running the command “npm install aws-sdk” in your Lambda function’s root directory. Alternatively, you can also use yarn by running “yarn add aws-sdk”. This will ensure that the package is installed and available for use in your Lambda function.
What if I’m using a monorepo and the AWS SDK package is installed at the root level?
If you’re using a monorepo and the AWS SDK package is installed at the root level, you may need to specify the relative path to the package in your Lambda function code. You can do this by using the “require” function with the relative path, for example: “const AWS = require(‘../../aws-sdk’);”. This will allow your Lambda function to correctly import the AWS SDK package.
Can I use Import statements instead of require?
Yes, if you’re using ES modules in your Lambda function, you can use import statements instead of require. For example: “import * as AWS from ‘aws-sdk’;”. This will allow you to import the AWS SDK package using ES modules.
What if I’ve tried all the above solutions and the error still persists?
If you’ve tried all the above solutions and the error still persists, it’s possible that there’s a more complex issue at play. Try checking your Lambda function’s deployment package to ensure that the AWS SDK package is correctly included. You can also try redeploying your Lambda function or checking the CloudWatch logs for more detailed error messages.
