Error using upload button with release 0.88.0

🎈 Using Streamlit

Dear all,
When I use a code which was working well with version 0.85 to upload some file, I get the error:
AttributeError: ‘google.protobuf.pyext._message.RepeatedScalarConta’ object has no attribute ‘uploaded_file_info’
My code is essentially: uploaded_file = st.file_uploader(“Upload your data”, type= (“xlsx”,“csv”))

It seems to come from: file_uploader.py", line 243. Here is the full error message:

Traceback:

Hi @victorstorchan, and welcome to the Streamlit community! :balloon::raised_hands:

Would you mind posting your code please?

Thanks

Hello! thank you for your answer.
My code is really only:

@Charly_Wargnier I would just be curious if you can reproduce the error: the command works well with version 0.85 but crash with the 0.88 version. Thanks for the great help :slight_smile:

Please try with " instead of “?

What do you mean? I need both to use the new download button which is only available with the 0.88. version and the file_uploader which does not seem to work with this version.

Your code works fine for me, yet you’d need to change the quotation marks
