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

The error being thrown is:
