[VCU118][firesim enumeratefpgas] can not generate a database file in /opt/firesim-db.json

[Ton Nguyen SInh]

Hi everyone, 
Based on the guide at https://docs.fires.im/en/1.17.1/Getting-Started-Guides/On-Premises-FPGA-Getting-Started/Repo-Setup/Xilinx-VCU118.html,
I executed the command "firesim enumeratefpgas".
However, this command did not generate a database file in the directory /opt/firesim-db.json.

What could be the issue? What am I missing?

Best regards,
TonNguyen

It also didn't generate this file for me, but it still worked.
