I am getting a ModuleNotFoundError when trying to invoke a Python Lambda function locally. However, if I browse to the URL it works perfectly fine. I have reduced the code down to almost nothing and its still throwing the error. Its basically just the default code from sls create with a folder to import a module with a **init**.py in the folder. The class has 1 method. Using Serverless Framework 1.32.0

As you can see its about as basic as you can get.  
root folder:  
drwxr-xr-x 4 mvivanco staff 136B Oct 16 15:31 dal/  
-rw-r–r-- 1 mvivanco staff 222B Oct 16 17:17 handler.py  
-rw-r–r-- 1 mvivanco staff 2.9K Oct 16 17:26 serverless.yml

dal folder contents:  
-rw-r–r-- 1 mvivanco staff 140B Oct 16 15:31 TeacherDAL.py  
-rwxr-xr-x 1 mvivanco staff 0B Oct 16 15:28 **init**.py

**init**.py is empty  
contents of dal/TeacherDAL.py  
class TeacherDAL(object):  
@staticmethod  
def getTeacher():  
return {“Name”:“John Doe”}

contents of handler.py  
import json  
from dal.TeacherDAL import TeacherDAL

def hello(event, context):  
result = TeacherDAL.getTeacher()  
response = {  
“statusCode”: 200,  
“body”: json.dumps(result)  
}  
return response

contents of serverless.yml  
service: temp6  
provider:  
name: aws  
runtime: python3.6

functions:  
hello:  
handler: handler.hello  
events:  
- http:  
path: /teacher/get  
method: get  
cors: true

The error being thrown is:
