sam local invoke throws cannot find module index error

Question

I'm trying to run a sam local invoke command within my Dockerfile setup and it goes well untill I get to the point of mounting my lambda function where it throws an erro:

This is my dockerfile

FROM python:3.9-slim

    apt-get install -y \
    curl \

# Install esbuild globally

# Build and invoke the Lambda function
CMD ["sh", "-c", "sam build && sam local invoke --container-host host.docker.internal --event events/game-dictionary-event.json GameDictionaryHandlerLambdaFunction"]

When I run the sam local invoke without host.docker.internal thing it gets stuck at the mounting /app.. step and don't go further. I'm thinking the error has to do something with it
