Unhandled Promise rejection: timeout ; Zone: <root> in angular 6

Question

When I use ng-recaptcha component while routing to another route.

Error is :

Unhandled Promise rejection: timeout ; Zone: ; Task: Promise.then ; Value: timeout undefined

Unhandled Promise rejection: timeout Zone: <root>; Task: Promise. then; 
Value: timeout undefined
./node_modules/zone.js/dist/zone.js/</</api.onUnhandledError
handleUnhandledRejection
loop 1
./node_modules/zone.js/dist/zone.js/</</api.microtaskDrainDone
drainMicroTaskQueue
./node_modules/zone.js/dist/zone.js/</ZoneTask.invokeTask
ZoneTask/this.invoke
timer

How could I resolve this error?
