Runtime.ExitError

[devdjdjdj]

I am getting the following error when trying to run even the most basic function

I'm seeing this error too -- in my case it's a consequence of trying to run in Python 2 rather than Python 3.

The code in runtime_client.cpp is written for Python 3 (see here), which means it can't be imported in my Python 2 image, which means this line silently sets runtime_client to None.

@devdjdjdj thanks for reporting this issue - could you please share your Dockerfile so that we can have a look into what might be going wrong with your function?

@azza-bazoo awslambdaric only supports Python versions 3.6 and up. I highly recommend you try to upgrade your function/application to a more recent Python version that's still being actively supported (Python 2.7 has been officially EOL for over a year now).

This is happening to me with the python:3.8-alpine base image. Here is the Dockerfile:

ARG build_info="head@now"
ARG build_env="development"

FROM python:3.8-alpine AS base

ARG build_info
ARG build_env

ENV PYTHONPATH=/function
ENV BUILD_INFO=${build_info}

WORKDIR /function
COPY . /function

RUN apk add --no-cache --virtual .build-deps \
    autoconf \
    automake \
    build-base \
    cmake \

    libexecinfo-dev \
    libstdc++ \
    libtool \
    make \
    postgresql-dev \
    python3-dev \
    && pip install --no-cache-dir -e . \
    && apk del --no-cache .build-deps

FROM base AS build-production
RUN echo " -> Building production image"

FROM base AS build-development
RUN echo " -> Building development image" \
    && apk add --no-cache \
    bash \
    vim \
    iputils \
    && pip3 install --no-cache-dir -e .[debug,testing]

Here's the entry.sh:

#!/bin/sh

    exec /usr/bin/aws-lambda-rie /usr/local/bin/python -m awslambdaric $1
else
    exec /usr/local/bin/python -m awslambdaric $1
fi

and here's the error:

Just to make sure, I ran docker exec -it mycontainer /bin/bash and typed /usr/local/bin/python --version, the response was Python 3.8.7
