- If (*messageWriter).createPart fails, w.err will be set and w.partWriter will be nil. - (*messageWriter).writeBody do not check the w.err and the w.partWriter. It may try to use the nil w.partWriter, causing "panic: runtime error: invalid memory address or nil pointer dereference". - Adding the check of w.err, just like (*messageWriter).Write, do nothing in (*messageWriter).writeBody if w.err is not nil.
