Can't create Lambda function using container runtime

Describe the bug I’m trying to create a lambda function using a container image runtime. It fails with the error:

botocore.errorfactory.InvalidParameterValueException: An error occurred (InvalidParameterValueException) when calling the CreateFunction operation: Runtime and Handler are mandatory parameters for functions created with deployment packages.

When I put Runtime and Handler parameters, it fails again with error:

botocore.errorfactory.InvalidParameterValueException: An error occurred (InvalidParameterValueException) when calling the CreateFunction operation: Please provide a source for function code.

I don’t see why do I have to put Runtime and Handler parameters with a container runtime, when those parameters are managed by the container itself. In the AWS console, you only need to specify the image URI. What am I doing wrong?

Steps to reproduce

import boto3

aws_session = boto3.Session()
lambda_client = aws_session.client('lambda', region_name='us-east-1')
image_uri = '1234567890.dkr.ecr.us-east-1.amazonaws.com/lambda-container:latest'

response = lambda_client.create_function(
    FunctionName='container_test',
    Role='arn:aws:iam::1234567890:role/lambda-role',
    Code={
        'ImageUri': image_uri
    },
    Timeout=600,
    MemorySize=1024
)

Expected behavior Create lambda function as container runtime with the URI image specified.

@vlall Here there is an example: https://github.com/lithops-cloud/lithops/blob/4aa42395fa7d9cf75eba708bd16064c094e71af2/lithops/serverless/backends/aws_lambda/aws_lambda.py#L330

@aitorarjona hi, I’m author of lua-aws and encountered same problem. in my case, problem is missing parameter. in brief, PayloadType = “Image” is required like this.

hope this helps you 👍
