Issue description

As I am adding a JWT authorizer, which is supposed to send requests to the Auth0 authorization server, to each endpoint’s Lambda function based on the deployment stage, I am receiving the error below when I tried to deploy by serverless deploy --stage local --region ap-east-1 --verbose:

yarn run v1.22.19
$ bash ./scripts/deploy-local.sh
$ tsc
make_bucket failed: s3://myapp-users-local-deployments-ap-east-1 An error occurred (BucketAlreadyOwnedByYou) when calling the CreateBucket operation: Your previous request to create the named bucket succeeded and you already own it.
To ensure safe major version upgrades ensure "frameworkVersion" setting in service configuration (recommended setup: "frameworkVersion: ^3.38.0")

Error:
Function "localAuthorizer" doesn't exist in this Service

Context

I have defined 3 authorizers under the provider section and each is used for a specific stage or a specific group of stages. Such implementation is based on the JWT Authorizers section of the docmentation here: Serverless Framework - AWS Lambda Events - HTTP API (API Gateway v2)

Each function uses a custom variable that is returned based on the deployment stage and originally defined as a set of function definitions. Each function definition in the set is stage-based and uses an authorizer, which is defined in the provider.httpApi section and corresponds to the deployment stage.

My serverless.yml is as follows:

// serverless.yml
custom:
  stageBasedFunction: # function definition for `dev`, `staging`, `canary`
