Issue with Blueprint and Pure Lambda Functions

I am using Blueprint for API endpoints and Pure lambda functions. I am able to successfully register my endpoints and hit them, but the lambda functions that interact with these endpoints are not being registered because I get an error message that says this: "errorMessage": "Handler 'function_name' missing on module 'app'","errorType": "Runtime.HandlerNotFound"

In the chalicelib directory, I have: __init__.py api_endpoints.py pure_lambdas.py

The app.py is setup like this:

from chalicelib.api_endpoints import api_endpoints
from chalicelib.pure_lambdas import pure_lambdas
app = Chalice(app_name='app-name')
app.experimental_feature_flags.update(['BLUEPRINTS'])
app.register_blueprint(api_endpoints)
app.register_blueprint(pure_lambdas)

The pure_lambdas.py is setup like this:

pure_lambdas = Blueprint(__name__)

@pure_lambdas.lambda_function(name='NAME')
def function_name(event, context):
        [code]

@pure_lambdas.lambda_function(name='NAME1')
def function_name1(event, context):
        [code]

When I keep the lambda functions within app.py, everything runs properly. I just can’t get it to work when I use Blueprint.

@madhavmehta1 I used the same app.py you had in your original comment. For completeness this is the app.py file:

$ tree
.
├── app.py
├── chalicelib
│   ├── __init__.py
│   ├── api_endpoints.py
│   └── pure_lambdas.py
└── requirements.txt

$ cat app.py
from chalice import Chalice
from chalicelib.api_endpoints import api_endpoints
from chalicelib.pure_lambdas import pure_lambdas

app = Chalice(app_name='app-name')
app.experimental_feature_flags.update(['BLUEPRINTS'])
app.register_blueprint(api_endpoints)
app.register_blueprint(pure_lambdas)

My api_endpoints.py and pure_lambdas.py are exactly what was shown in my previous comment.

@rajpdus The documentation says the concept is extended to ALL Chalice resources:

Note The Chalice blueprints are conceptually similar to Blueprints in Flask. Flask blueprints allow you to define a set of URL routes separately from the main Flask object. This concept is extended to all resources in Chalice. A Chalice blueprint can have Lambda functions, event handlers, built-in authorizers, etc. in addition to a collection of routes.
