What is wrong with this?

Code:

public Action:Event_PlayerTeam(Handle:event, const String:name[], bool:dontBroadcast)
{
	new client = GetClientOfUserId(GetEventInt(event, "userid"));	
	if (IsFakeClient(client))
	{
		return;
	}
	// some code
}

Error:

Code:

[SM] Native "IsFakeClient" reported: Client index 0 is invalid

Tried to add function that prints to chat current client value for diagnostic but it tells me 21 (not 0).
