Bug: "sam build - TypeError" When building Docker Image from documentation
Description:
I am trying to build a Docker image for AWS SAM. The issue is that the code from the AWS SAM documentation doesn't work and crashes.
Steps to reproduce:
Go here and marvel at the four year old documentation which talks about a sam init that no longer supports docker: https://aws.amazon.com/blogs/compute/using-container-image-support-for-aws-lambda-with-aws-sam/
Create these three files:
app.py:
import json
def lambda_handler(event, context):
response = {
"statusCode": 200,
"body": json.dumps({
"message": "Hello, World!"
}),
}
return response
Dockerfile:
FROM public.ecr.aws/lambda/nodejs:12
COPY app.js package.json ./
RUN npm install
CMD ["app.lambdaHandler"]
template.yml:
Resources:
HelloWorldFunction:
Type: AWS::Serverless::Function
Properties:
PackageType: Image
Events:
HelloWorld:
Type: Api
Properties:
Path: /hello
Method: get
Metadata:
DockerTag: nodejs12.x-v1
DockerContext: ./hello-world
Dockerfile: Dockerfile
Observed result:

Hey there,
There are some issues with the example that you shared. It seems like you are trying to build an application which is written with python (app.py) in a nodejs image. You should be using python images for your application https://gallery.ecr.aws/lambda/python
For easiest start, I will recommend running sam init and making selections for your preference. In that way, you should have a valid and running project setup ready.
