Hello,

After reinstalling the version from scratch on Docker, it works well now. So, it’s likely a problem on my side.

hey, can you elaborate on what you did? are you running Flowise using a base image? or is a different solution?

@HenryHengZJ maybe this issue is related to #3645 , which you closed by Dec 2024, but at least 4 users (including me) reported on that thread the issue remains, but the ticket is still closed (and for sure, out of your sight)

Hi there,

I want to clarify my testing process. Initially, I tested with a fresh local installation using the API endpoints directly, which seemed to work. This led me to believe the issue was resolved.

However, I've since confirmed the problem still exists in two scenarios:

When using the Flowise UI interface (both in Docker and local installations)
When using API endpoints within Docker (as detailed in issue #4228)

I'm running Flowise using both methods:

Direct local installation
Docker container using the official image

I've reopened this issue since the document upload functionality remains broken in the UI across all installation methods.

I have this exact issue, and I know one other person on their system is having this exact issue. The Flowise 2025 tutorial on YouTube actually walks through setting this up during the output parsing session. In his video everything worked as he was slightly back-rev'd on his flowise, but everyone going through this now is going to hit this issue.
