Describe the bug
I just expected it to not throw an error. Anchoring itself works just fine.

Do you have an error log of what happened?

4x Action[SetPoint] failed because[SetPoint would result in anchor family connection]: attempted from: <unnamed>:SetPoint.

To Reproduce

Import: https://wago.io/P1h-c2a6L
reveal an enemy nameplate

Did you try having WeakAuras as the only enabled addon and everything else (especially something like ElvUI) disabled?
yes

Which version of WeakAuras are you using?
master but seems to happen on any version

Additional context
recent ptr patch might've caused it

The method which is encountering an error is this:

local function UpdatePosition(self)
  if (not self.anchorPoint or not self.relativeTo or not self.relativePoint) then
    return;
  end

  local xOffset = self.xOffset + (self.xOffsetAnim or 0);
  local yOffset = self.yOffset + (self.yOffsetAnim or 0);

  xpcall(self.SetPoint, geterrorhandler(), self, self.anchorPoint, self.relativeTo, self.relativePoint, xOffset, yOffset);
end

Since you wrote this code:

function()
    if aura_env.state and aura_env.state.PassUnit then
        local region = aura_env.region
        local plate = C_NamePlate.GetNamePlateForUnit(aura_env.state.PassUnit)
        if plate then
            region:ClearAllPoints()
            region:SetPoint("BOTTOM", plate, "TOP", 0, 0)
            region:Show()
        else
            region:Hide()
        end
    end
end

The actual attachment point is not what WeakAuras expects, and since you did not notify WeakAuras of this via SetAnchor, you are seeing an error message.

In the future, use SetAnchor as has been recommended to you previously.
