Bug: [Error Log] [counters] Intermittent error logs seen from syncd while running port_rate lua plugin #24342
Description
Is it platform specific
generic

Critical
Description of the bug
Seen for a few seconds after reboot (only sometimes). So, not 100% reproducible.
Error is coming from port_rates.lua script but harmless, since after the first set of errors, the rates are populated correctly'
