Question

I'm new to AWS. TIA

Answer 1

AWS Lambda's are missing some postgres libraries, and the standard psycopg2 library will not work.

A solution to this is to use a different psycopg2 library from here - https://github.com/jkehler/awslambda-psycopg2 inside of your project, instructions on how to add it as a package within AWS Lambda are in the repo.

1. Build the layer package using the structure "python/lib/python3.9/site-packages".

2. After installing psycopg2-binary, rename the _psycopg.so file under the directory "psycopg2" ("_psycopg.cpython-39-x86_64-linux-gnu.so "is under the "psycopg" directory).

3. Put the layer into the Python lambda function and add it to the code.
