How to include a file for importing objects in aws lambda that is a custom resource for cdk v2?

Question

I am using python 3.8 as the lambda runtime for my lambda function which I am trying to deploy using cdk v2. This is a lambda as a custom resource that runs every time the stack deploys.

This is the folder structure

 /Dynamics/cust_resource/__init__.py
 /Dynamics/cust_resource/data_objects.py
 /Dynamics/cust_resource/lambda.py
 /Dynamics/cust_resource/requirements.txt
 /Dynamics/__init__.py
 /Dynamics/dyna_stack.py
 app.py

This is the lambda code

import os
import boto3
import sys
 
print('before lambda import') 

from data_objects import poco_data

This is how I am creating the function in the stack

cust_res_lambda = _lambda.Function(
    self, 'crLambda',
    runtime=_lambda.Runtime.PYTHON_3_8,
    code=_lambda.Code.from_asset('Dynamics/cust_resource',
                                 bundling=BundlingOptions(
                                        image=_lambda.Runtime.PYTHON_3_8.bundling_image,
                                        command=["bash", "-c", "pip install -r requirements.txt -t /asset-output && cp -au . /asset-output"]
                                     )),
    handler='lambda.lambda_handler',
    function_name='crlambdaFn',
    
)

The lambda executes and I see the line before lambda import in cloudwatch logs followed by.

What does this error mean and how to fix it?
