I only modified the internal structure of the function and ran the TestConvertBigIntArrayToString test. The result passed successfully.

stringArray := make([]string, len(array))
var sb strings.Builder
sb.Grow(len(array) * 22)
for i, num := range array {
stringArray[i] = num.String()
if i > 0 {
sb.WriteString(", ")
}
sb.WriteString(num.String())
}

result := strings.Join(stringArray, ", ")
return result
return sb.String()
}

// ConvertStringToStringArray takes a string with values separated by commas and returns a slice of strings
