I got this error when the code is run in a goroutine (not sure exactly what the cause is, but it happens from time to time, and only happens to that line, all the other places where I use kw.Logger.Println never gives an error)
kw.Logger.Println("KafkaWorker Starts Listening.") // << the error happens here!!!!!!!!!!!!!!!![All 2 KafkaWorkers Start Listening...

@inhere after checking my call stack, it seems it is triggered by possible negative value of the times being negative from func RepeatChars[T byte | rune](char T, times int) []T at [email protected]/strutil/padding.go
from my particular case, the times becomes -2, probably needs to change
if times == 0 {
return make([]T, 0)
}into
if times <= 0 {
return make([]T, 0)
