The problem is than the i var in time function is always 0 at start of any time() call then though you inctement it (its temporary and not global). Inside time() uoua will get a reference to button and if i<1 you remove it BUT its always the case then you will access to a null refetence to button (returned by getElementById) and, without checks, you try to access to a field of null object raising an exception

you have to declare let i = 0; outside the time function. otherwise it will always be 0.
