transform(profilePictureUrl: string): any {
    return this.methodA(profilePictureUrl).then((res)=>{
        return res;
    })
}

private async methodA(pPUrl: string) {
    var accessCredentials = await SDKInitializer.GetInstance().GetSessionCredentials();
    return accessCredentials.AccessToken
}

In the above method GetSessionCredentials() returns a promise which i want to resolve by using then() and return its value.

It returns me this ZoneAwarePromise {zone_symbol__state: null, __zone_symbol__value: Array(0)} __zone_symbol__state: true __zone_symbol__value: "braj ankit" __proto: Object

Yes, `transform` will return a promise. You need to handle it the same way you're already handling promises: either with `transform(...).then(...)`, or with `await transform(...)`. – deceze May 21 '19 at 15:31
is there any another way ? – Braj Ankit May 21 '19 at 15:33
No, there is not. – deceze May 21 '19 at 15:34
