I have uploaded my function code (.zip) to the S3 bucket (in us-east-1 region). I want to launch a lambda function using the CloudFormation template. When I am launching the template from us-east-1 region, I am getting s3:getObject error. The s3 bucket is publicly accessible.

This is my function.yaml which creates the lambda function here I have put the environment variables but it’s shared all across the lambda function stack I make function.yaml

Could anybody help me with Cloudformation stack?
I tried to update cloudformation stack but fails and its says “,,, securitygroup is in use by …lambda”
I manually deleted this securitygroup and lambda. but the error still keeps.
how to resolve this?
