Databricks App - Streamlit file Upload issue

SanthanaSelvi06 — Wed, 20 Aug 2025 09:53:35 GMT

I used this code snippet from cookbook and created a custom databricks streamlit app to upload files to the volume but i am getting the following error even before start uploading it to volume. Using file_uploader in streamlit while uploading the file from my computer, I got this error.

AxiosError: Request failed with status code 403

Did anyone faced similar issue? FYI I am using databricks community/free edition
