Error invalid dynamic link domain (action code settings)

[ANIBIT14]

For implementing Email Link Sign In when I am defining action code settings with dynamicLinkDomain key and passing the needed dynamic link url to it, the following error is being thrown -:
[Error: [auth/invalid-dynamic-link-domain] The provided dynamic link domain is not configured or authorized for the current project.]

but when I am not using the above key it picks up the default dynamic link and everything's works, but as our project ha multiple apps I needed the dynamic link url of my choice to use.

Hope anybody can tell how to resolve the above error

In your Firebase console, go to Authentication -> Sign-in method, scroll down to Authorized domains. Make sure you've added your dynamicLinkDomain to that list.
