HandlerNotFound Error After Moving Lambda Function to Module in Chalice

I have a Lambda function deployed with Chalice that is triggered by an SQS queue event. After refactoring my code to move the function from the main app.py file to a module and registering the module via a blueprint, I started receiving the following error:

```
[ERROR] Runtime.HandlerNotFound: Handler 'any_handler' missing on module 'app'
Traceback (most recent call last):
```

api.py
```
from chalice import Blueprint

api = Blueprint(__name__)

@api.on_sqs_message(
queue='queue_name',
batch_size=1
)
def any_handler(event):
# Function logic here
```

app.py:
```

from chalice import Chalice
from chalicelib.api import api, handle_http_errors

app = Chalice(app_name='app_name')

app.api.binary_types = ['application/x-protobuf']
app.register_blueprint(api)

app.register_middleware(handle_http_errors, 'http')

```
Chalice version: 1.31.0

Start with the deployment setup shown in app.py and chalicelib/api.py, using Chalice 1.31.0 and the SQS-triggered any_handler. Reproduce the deployment and inspect how registering the blueprint affects the Lambda handler entry point. Done means the deployed SQS function invokes any_handler without Runtime.HandlerNotFound.
