(aws_cdk.aws_dynamodb): adding replication_regions to Table construct causes build/deploy errors

[vitaliknet]

General Issue

"sam-beta-cdk build" fails with replication_regions defined in aws_dynamodb.Table

The Question

sam-beta-cdk build fails with replication_regions parameter, but builds successfully when replication_regions line is commented out.

from aws_cdk import App, Stack
from aws_cdk import aws_dynamodb as dynamodb

from constructs import Construct

class MyStack(Stack):
    def __init__(self, scope: Construct, construct_id: str, **kwargs) -> None:
        super().__init__(scope, construct_id, **kwargs)

        global_table = dynamodb.Table(self, "Table",
            partition_key=dynamodb.Attribute(name="id", type=dynamodb.AttributeType.STRING),
            replication_regions=["us-east-1", "us-west-2"]
        )

app = App()
MyStack(app, "dynamodb-test")

app.synth()

sam-beta-cdk build

Other information

I came across this error in an attempt to troubleshoot cdk deploy failure of a more complex CDK app with multiple stages/stacks. When replication_regions is defined in aws_dynamodb.Table, the nested replication stack fails to create IsCompleteHandler7073F4DA and OnEventHandler42BEBAE0 resources:

Resource handler returned message: "Uploaded file must be a non-empty zip (Service: Lambda, Status Code: 400, Request ID: c2cd5506-2d68-4862-967f-2a61a8ab9b5e, Extended Request ID: null)" (RequestToken: 9e70ee27-c2b2-a433-6301-1db455fc1438, HandlerErrorCode: InvalidRequest)

Resource handler returned message: "Uploaded file must be a non-empty zip (Service: Lambda, Status Code: 400, Request ID: 87ddb923-6358-4643-b5a8-a1dca704bb44, Extended Request ID: null)" (RequestToken: 86c51774-2eca-3f8c-85bc-ce8d9c7ab84b, HandlerErrorCode: InvalidRequest)

Hey @vitaliknet,

thanks for opening the issue. To help me pin-down the problem, can you tell me whether you get the same problem when using pure CDK, without sam-beta-cdk? So, when running cdk synth / cdk deploy?

Thanks,
Adam

Hi @skinny85 -

the issue was indeed coming from sam-beta-cdk, as discussed in aws/aws-sam-cli#2849

The original "Uploaded file must be a non-empty zip" issue was related to node version, addressed in serverless/serverless#8772 (comment).

Thanks!
