Need Help Resolving Error When Downloading Settlement Report

[hafizawani8a0d]

Hi everyone,

I'm a beginner in Magento, and I've been tasked by my boss to resolve an issue we're facing when trying to download a settlement report. The error message we’re getting is:

This error seems to occur in the ConvertToCsv.php file. Since I’m new to Magento, I’m not sure how to resolve this. Could someone guide me on what might be causing this issue and how I can fix it?

Hi @hafizawani8a0d,

Issue is coming from Fbl module, either it is custom or 3rd party.
You may need to debug in the codebase.
