When you are in a team, but you are not the leader, and you can still click to apply for a team at this time,In fact, the "sign up" button is not available. At this time, an error will occur and you must log in again.

The following code is to fix this BUG

hooksecurefunc("LFGListSearchEntry_OnClick", function (self, button)
if not PremadeGroupsFilterSettings.oneClickSignUp then return end

local panel = LFGListFrame.SearchPanel
if button ~= "RightButton" and LFGListSearchPanelUtil_CanSelectResult(self.resultID) and panel.SignUpButton:IsEnabled() then
    if panel.selectedResult ~= self.resultID then
        LFGListSearchPanel_SelectResult(panel, self.resultID)
    end
    LFGListSearchPanel_SignUp(panel)
end

end)
