localstack serverless deploy is not getting deployed - amazon-web-services

Question

I am trying to deploy my serverless project locally with LocalStack and serverless-local plugin. When I try to deploy it with serverless deploy it throws an error and its failing to create the cloudformation stack.But, I manage to create the same stack when I deploy the project in to real aws environment. What is the possible issue here. I checked answers in all the previous questions asked on similar issue, nothing seems to work.

I fixed that problem using this plugin: https://www.serverless.com/plugins/serverless-deployment-bucket

You need to make some adjustments in your files.
Update your docker-compose.yml, use the reference docker compose from
localstack, you can check it here.
Use a template that works correctly, AWS docs page have several
examples, you can check it here.
Run it with next command aws cloudformation create-stack --endpoint-url http://localhost:4566 --stack-name samplestack --template-body file://lambda.yml --profile dev
You can also run localstack using Python with next commands
pip install localstack
localstack start
