Write data node fails with "unknown error... process got killed by the server" when outputting sorted data

[AmandeepS1ngh]

I am experiencing a process crash when running a flow containing a large dataset (Yelp database CSV, ~1 million rows, 110 MB) in Performance mode.

The flow consists of:

Read data (loading yelp_database.csv)
Filter data (filtering by rating and reviews)
Sort data (sorting the filtered rows by reviews)
Write data (saving the output to a CSV file)
During execution, the Write data node fails after 5-6 seconds with the following error: Error: There was an unknown error with the process, and the process got killed by the server

I have confirmed that:

The target output path is a valid absolute path with write permissions.
The output file is not open or locked in any other application.

Environment:
OS: Windows
Flowfile version: 0.11.2

@AmandeepS1ngh, Thanks for raising it! What was the location that the write output was writing to? If "." then it will be resolved in the latest release.

The location I was writing to is a full absolute path on Windows, not ".":

• Folder: C:\Users\amand\Desktop\flowfiles Workflows
• Filename: output.csv

@AmandeepS1ngh, Can you try to reproduce this with the latest version?
