Well, I can't tell you why that doesn't work with WeakAuras I don't use it, but you can reduce quite a bit of duplication in your code:

	local name, _, _, _, _, _, expirationTime = UnitBuff("player", "Lifebloom", nil, "PLAYER")
	if name then
		return expirationTime or 0
	end
	if not IsInGroup() then
		return
	end

	local unit, n = "raid", GetNumGroupMembers()
	if not IsInRaid() then
		unit, n = "party", n - 1
	end
	for i = 1, n do
		local name, _, _, _, _, _, expirationTime = UnitBuff(unit..i, "Lifebloom", nil, "PLAYER")
		if name then
			return expirationTime or 0
		end
	end
