TypeError: path should be path-like or io.BytesIO, not <class 'NoneType'>

🎈 Using Streamlit

hi
I am new to Streamlit and programming.
I keep getting this error message in my app.py.
Can you help ?

line 31 : image = image.load_img(uploaded_file)
buffer = io.BytesIO() # create file in memory
image.save(buffer, ‘jpeg’) # save in file in memory - it has to be jpeg, not jpg
buffer.seek(0) # move to the beginning of file
bg_image = buffer # use it without open()

error message:
2022-07-27 12:25:15.189 Uncaught app exception

Make sure uploaded_file is not None.

I can display the uploaded file.

Not sure what you mean by that. The error message is telling you that uploaded_file is None when you call image.load_img(uploaded_file) in line 31.

Okay. Thanks. Let me check
