aws-lambda-python-alpha: Bundling - AssetHashType.OUTPUT failing cdk destroy

[edwardgale]

Describe the bug

RuntimeError: Cannot use output hash type when bundling is not specified.

cdk destroy and cdk destroy --no-staging both failing because we have the following bundling options for our lambda:

lambda_alpha.BundlingOptions(
            asset_excludes=exclusions,
            asset_hash_type=AssetHashType.OUTPUT,
            volumes=[
                DockerVolume(
                    host_path=lib_dir,
                    container_path="/asset-input/lib",
                )
            ],
        )

We create the hash on the Output because our exclusions list is large and some files in the exclusions list are dynamic leading to changes in hash and unnecessary redeployments.

Expected Behavior

cdk destroy and cdk destroy --no-staging should destroy the stack. Creating a hash type of OUTPUT has no relevance here.

Current Behavior

The following stack trace was emitted:

jsii.errors.JavaScriptError:

Reproduction Steps

Create a python lambda function with the following options:

        lambda_alpha.PythonFunction(
            self,
            "MyFunc",
            entry="/path/to/src",
            index="app.py",
            handler="lambda_handler",
            bundling=lambda_alpha.BundlingOptions(
                asset_hash_type=AssetHashType.OUTPUT,
            ),
            runtime = lambda_.Runtime.PYTHON_3_10
        )

deploy and run cdk destroy --no-staging

RuntimeError: Cannot use output hash type when bundling is not specified.

I didn't get it. According your repro steps, you actually provided the bundling prop, didn't you?

lambda_alpha.PythonFunction(
            self,
            "MyFunc",
            entry="/path/to/src",
            index="app.py",
            handler="lambda_handler",
            bundling=lambda_alpha.BundlingOptions(
                asset_hash_type=AssetHashType.OUTPUT,
            ),
            runtime = lambda_.Runtime.PYTHON_3_10
        )

Bundling prop was provided. However asset_hash_type=AssetHashType.OUTPUT still fails a cdk destroy

Very basic repo to reproduce the issue here:

Seeing this with node functions on deploy as well btw. lmk if more info is required or you'd prefer it in another issue <3 ty
