You need the sqlite3.so file (as others have pointed out), but the most robust way to get it is to pull from the (semi-official?) AWS Lambda docker images available in lambci/lambda. For example, for Python 3.7, here's an easy way to do this:

First, let's grab the sqlite3.so (library file) from the docker image:

mkdir lib
docker run -v $PWD:$PWD lambci/lambda:build-python3.7 bash -c "cp sqlite3.cpython*.so $PWD/lib/"

Next, we'll make a zipped executable with our requirements and code:

pip install -t output requirements.txt
pip install . -t output
zip -r output.zip output

Finally, we add the library file to our image:

cd lib && zip -r ../output.zip sqlite3.cpython*.so

If you want to use AWS SAM build/packaging, instead copy it into the top-level of the lambda environment package (i.e., next to your other python files).
