I can make inference from my trained Roboflow model using Google Colab and the AWS cloud9 test environment.

To do this, I used the following code:

from roboflow import Roboflow

rf = Roboflow(api_key="xxxxxxxxxxxxxxxxx")
path = "/context/image.jpeg"
project = rf.workspace().project("xxxxxx")
model = project.version(x).model

# infer on a local image
currency_result= model.predict(path, confidence=40).json()```

However, when I put it into production I got the following error:

    [ERROR] TypeError: expected str, bytes or os.PathLike object, not NoneType
Traceback (most recent call last):

  File "/var/lang/lib/python3.8/posixpath.py", line 76, in join

What I found interesting was that I was able to run the code in cloud9 using sam local invoke, but in the production environment I got the above error.
