Unzipped size must be smaller than 262144000 bytes - AWS Lambda Error

I have tried to upload my application using servless/lambda function AWS, but i got this issue:

An error occurred: AppLambdaFunction - Unzipped size must be smaller than 262144000 bytes (Service: AWSLambdaInternal; Status Code: 400; Error Code: InvalidParameterValueException; Request ID: 8ea0d887-5743-4db1-96cd-6c5efa57b081).

What is the best way to resolve it?

Look my dependencies:

  "dependencies": {
    "ethereumjs-tx": "^1.3.7",
    "aws-sdk": "^2.4.52",
    "body-parser": "^1.18.3",
    "compression": "^1.7.4",
    "consign": "^0.1.6",
    "cors": "^2.8.5",
    "express": "^4.16.4",
    "helmet": "^3.16.0",
    "moment": "^2.24.0",
    "openzeppelin-solidity": "^2.3.0",
    "serverless": "^1.48.2",
    "serverless-http": "^1.9.1",
    "serverless-offline": "^4.9.4",
    "truffle": "^5.1.9",
    "truffle-hdwallet-provider": "^1.0.17",
    "web3": "^1.2.5-rc.0"
  },

Serverless.yml:

provider:
  name: aws
  runtime: nodejs8.10
  stage: v1
  region: us-east-1
  timeout: 30
  memorySize: 512
  package:
    excludeDevDependencies: true
    exclude:
      - .git/**
      - .vscode/**        
      - venv/**

functions:
  app:  
    handler: handler.run
    events:
      - http:
          path: /
          method: ANY
          cors: true
      - http:
          path: /{proxy+}
          method: ANY

I ran into this issue once I started depending on the boto3 library.

After trying lots of different things, I learned that this package comes pre-installed with the AWS Python runtime so you can either leave the dependency undeclared or make it a dev dependency.

Recently i faced the same issue, my total package size was more than 40mbs and it was also including the venv (python virtual environment) folder that resides in the project directory. I excluded it and build size got reduced to 16 mbs. and the project was deployed successfully. I added the following in serverless.yaml

package:
  patterns:
    - '!node_modules/**'
    - '!venv/**'
    - '!apienv/**'
    - '!__pycache__/**'

Adding exclude under package is deprecated. We can use pattern to remove node_modules.

Example to remove files in the serverless.yml

...remaining props
package:
  patterns:
    - '!.git/**'
    - '!test/**'
    - '!e2e/**'
    - '!src/**'
    - '!node_modules/**'

Deprecation for exclude and Pattern

See my answer here

You can deploy a Lambda function using a Docker image and it bypasses this problem, allowing a function with its dependencies to be as large as 10 gb.

I've had success resolving this error message using the serverless-esbuild plugin, and configuring it as follows in serverless.yml:


service: service_name
frameworkVersion: '3'
provider:
  name: aws
  runtime: nodejs12.x

plugins:
  - serverless-esbuild

custom:
  esbuild:
    bundle: true
    minify: false
    sourcemap: true
    exclude: 'aws-sdk'
    target: node14
    define:
      'require.resolve': undefined
    platform: node
    concurrency: 10

Use the directive exclude at your serverless.yml file. In case of Python, I've been used it as follows:

package:
  exclude:
    - node_modules/**
    - venv/**

The build process will exclude them from the build before sending to AWS.

Tip I got in this issue at Github. The documentation for this directive is detailed here.

You can use module bundlers to package the code.

Using module bundlers such as webpack

You can consider using plugins like serverless-webpack. The serverless-webpack plugin is using webpack to build the project and it will only include the bare minimum files required to run your application. It will not include the entire node_modules directory. so that your deployment package will be smaller.

a note about using of Lambda layers

Like others mentioned, you can use the layers and move some of the libraries and code to the layer. Layers are mainly used to share code between functions. The unzipped deployed package including layers cannot exceed 250MB.

hope this helps.
