pgp decryption and lambda

I try to use pgp encyption/decryption using lambda and found https://www.youtube.com/watch?v=N3R1SScBS9E&ab_channel=AmazonWebServices github: https://github.com/aws-samples/pgp-decryption-for-transfer-family?sc_channel=EL&sc_campaign=Demo_2022_vid&sc_medium=YouTube&sc_content=N3R1SScBS9E&sc_detail=MIGRATION_TRANSFER&sc_country=US basically i run setupenviroment.sh that create a lambda layer. I then create a very basic lambda funciton

import gnupg import json def lambda_handler(event, context): gpg = gnupg.GPG(gnupghome='/tmp', gpgbinary='/opt/python/gpg', options=['--trust-model', 'always'])

but i am keep getting error START RequestId: 72c1cffb-12ea-47f6-9d7f-dad91503e8b2 Version: $LATEST [ERROR] 2023-01-04T16:13:00.757Z 72c1cffb-12ea-47f6-9d7f-dad91503e8b2 Unable to run gpg (/opt/python/gpg) - it may not be available.
