serverless deploy error - Resource handler returned message: "Lambda function xxxxxxxx could not be found" - serverless

Question

Hi can anyone help me how to deploy serverless with specific stage, I have 1 app with 2 stage dev and prod. When deploy to dev its working fine and successfully deployed, but with prod stage always get below error:
Error:
UPDATE_FAILED: FilterOptionLambdaFunction (AWS::Lambda::Function)
Resource handler returned message: "Lambda function xxxxxxx-api-prod-xxxxxx could not be found" (RequestToken: ee621797-de45-aa3f-118b-8f512d4a5f62, HandlerErrorCode: NotFound)
I tried to comment all function and leave 1 function to test deploy, but received another error as below:
Error:
UPDATE_FAILED: EnterpriseLogAccessIamRole (AWS::IAM::Role)
Unable to retrieve Arn attribute for AWS::Logs::LogGroup, with error message Resource of type 'AWS::Logs::LogGroup' with identifier '{"/properties/LogGroupName":"/aws/lambda/xxxxx-api-prod-api"}' was not found.
Here is my serverless.yml:

I am guessing from those UPDATE_FAILEDs, you are using the same serverless file for both dev and prod deployment. Based on this assumption, you may have to provide separate service names for both of your deployments. If you have deployed to the dev environment already with service name comeby-scheduler-api, the next deployment for prod stage with the same service name will try to override the previous deployment.
In my case, I tackled this using 2 separate serverless configuration files (one for dev and the other for prod). For dev deployment, my config file serverless-dev.yml looks like the following.
service: service-dev
provider:
name: aws
role: arn:aws:iam::<aws-account-id>:role/<my-lambda-role-name>
region: <region>
runtime: python3.8
environment:
DB_HOST: <host>
DB_PASSWORD: <pass>
DB_PORT: <port>
DB_DATABASE: <db_name>
DB_USER: <db_user>
plugins:
- serverless-python-requirements
- serverless-secrets-plugin
- serverless-api-compression
package:
patterns:
- '!venv/**'
- '!__pycache__/**'
- '!node_modules/**'
- '!test/**'
functions:
Lambda1:
handler: lambda_file_name.handler_function_name
memorySize: 512
timeout: 900
events:
- s3:
bucket: <bucket_name_for_this_lambda_trigger>
event: s3:ObjectCreated:*
rules:
- prefix: <filter_trigger_file_prefix>
- suffix: <filter_trigger_file_suffix>
existing: <true if an existing s3 bucket, false otherwise>
Whereas for the prod, the serverless-prod.yml file is,
service: service-prod
provider:
name: aws
role: arn:aws:iam::<aws-account-id>:role/<my-lambda-role-name>
region: <region>
runtime: python3.8
... rest is similar
My deployment commands for these separate stages are.
sls deploy -s dev -c serverless-dev.yml
sls deploy -s prod -c serverless-prod.yml
