The function modifies the tags array parameter by reference, which could cause side effects for callers. Consider creating a copy of the tags array before modification: const newTags = [...(tags || []), \version:${version}`]and usenewTags` for the stats call.

Suggested change

	tags?.push(`version:${version}`)
	statsClient?.incr('dv360_api_version', 1, tags)
	const newTags = [...(tags || []), `version:${version}`]
	statsClient?.incr('dv360_api_version', 1, newTags)
