LAMBDA_RUNTIME Failed to get next invocation. No Response from endpoint. Only in pnpm sst dev.

[alfa-meta]

Original Issue. https://github.com/aws/aws-lambda-python-runtime-interface-client/issues/142#issue-2295029202

Then I learned that it only happens in pnpm sst dev.

Thing to note. This code worked perfectly two weeks ago. Not only that, I received the same error on this dockerfile too:

FROM ubuntu:latest

RUN apt update -y
RUN apt install python3 -y
RUN apt install python3-pip -y
RUN mkdir /var/task
RUN pip install awslambdaric --target /var/task

WORKDIR /var/task

# Copy the current directory contents into the container at /var/task
COPY . /var/task 

RUN chmod +x /var/task/tester.py
RUN chmod +x /var/task/entry_script.sh

ENTRYPOINT [ "/var/task/entry_script.sh" ]
CMD ["tester.handler"]

Where tester.handler is a function that returns the event from AWS Lambda. The thing is in no case does the lambda ever reach a single line of code in the handlers.

Currently using Ubuntu 24.04. Has been tested on Ubuntu 22.04 and the same behaviour has been observed (On a different machine).

What seems to be the case is that sst dev is unable to AWS resources with awslambdaric. I have tested this locally with just docker and it works. I have tested this in prod/aws resources and it works. It only does not work when using pnpm sst dev.

Before you say it might be how I setup my routes thats not possible either cause I have had the container work via sst dev before, it seems to be a new development.
