CSV File upload failing

[turtle3791]

Hi,

1. I have downloaded the following zip file
   https://www.stats.govt.nz/assets/Uploads/Marriages-civil-unions-and-divorces/Marriages-civil-unions-and-divorces-Year-ended-December-2020/Download-data/marriages-civil-unions-and-divorces-year-ended-december-2020-csv.zip
2. Extracted the CSVs in the zip files (all of the file are 2kb or less).
3. Wento to https://data-visualization-frontend-gamma.vercel.app/?ref=blog.langchain.dev
   When I try to upload the files I get the error "Failed to upload file" for all the files.
   I am using chrome Version 126.0.6478.115 (Official Build) (x86_64)
   Is there a issue with the code?
   Thank you
