I'm trying to develop a simple serverless app using Serverless framework and Python.
Here's my serverless.yml
service: hello-world
provider:
name: aws
region: us-west-2
runtime: python3.7
environment:
DB_ENDPOINT:
DB_USERNAME:
DB_PASSWORD:
plugins:
- serverless-python-requirements
functions:
hello:
handler: handler.trial_registration
When I run sls deploy
I get following error
Serverless: Generated requirements from /home/ganesh/code/hello-world/requirements.txt in /home/ganesh/code/hello-world/.serverless/requirements.txt...
