Building container image for AWS Lambda fails - python-3.x

Question

I want to deploy a container image with some Python libs and Python code which should be used as AWS lambda function. I followed the following blog post:
https://aws.amazon.com/de/blogs/machine-learning/using-container-images-to-run-pytorch-models-in-aws-lambda/
Locally on my machine I can build and run the Docker image successfully. From Docker perspective I thought this is ok. But when I use AWSSAMCLI, I get the following issue:
F:\AWS>sam build && sam deploy --guided
Your template contains a resource with logical ID "ServerlessRestApi", which is a reserved logical ID in AWS SAM. It could result in unexpected behaviors and is not recommended.
Building codeuri: F:\AWS runtime: None metadata: {'Dockerfile': 'Dockerfile', 'DockerContext': 'F:\\\AWS\\inference-ai'} architecture: x86_64 functions: InferenceFunction
Building image for InferenceFunction function
Setting DockerBuildArgs: {} for InferenceFunction function

F:\AWS>
I have no idea why an invalid file will be used (colon character). How can I solve this issue?
