Internal Server Error on Firmware Upload in Flask Application

[huntercu]

Hello,

I'm currently experiencing an issue with my Flask application and need some assistance. The application starts normally, and I can access the frontend via the browser on port 5000. However, when I try to upload firmware, I encounter an "Internal Server Error" in the browser.

Here is the error message displayed in the browser:

Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
Below is the relevant error log from the application:

Exception: No available plug-ins found. FACT backend might be down!
The error suggests that there are no available plugins and that the FACT backend might be down. Here is the portion of the code where the exception is raised:

def get_available_analysis_plugins():
raise Exception('No available plug-ins found. FACT backend might be down!')
I've checked and ensured that the backend service appears to be running, but the error persists.

Could you please provide guidance on how to resolve this issue? Any help or suggestions would be greatly appreciated!

Thank you in advance.
