Did you try restarting ng serve? – Derek Kite May 13 '20 at 04:29
many time restart but give same error – Anil Kumar Pal May 13 '20 at 04:55
It only exists from angular 6.1. You can define your own pipe if upgrading angular is not an option : https://stackoverflow.com/a/49772435/1160794 – David May 13 '20 at 07:08
