Firebase invites links through mail giving 404 error

I have firebase invites in my app. I send invites through mail and messages for both ios and android plateforms. When i send it through messages, it works fine in both the devices, it opens app in play store in android and app in app store in iphone. But when i send the invitations through mail, on clicking on the install link, it gives 404 error.

link description here

This is the link i get when i open it in android or iphone.

This is the code i am using to invite.

// Invite friends
id<FIRInviteBuilder> inviteDialog = [FIRInvites inviteDialog];
[inviteDialog setInviteDelegate:self];


FIRInvitesTargetApplication *targetApplication = [[FIRInvitesTargetApplication alloc] init];
targetApplication.androidClientID = @"android_client_id";
[inviteDialog setOtherPlatformsTargetApplication:targetApplication];    
NSString *message = [NSString stringWithFormat:SHARE_MESSAGE];

[inviteDialog setMessage:message];

[inviteDialog setTitle:@"Invite Friends"];

[inviteDialog open];

Please help me with this issue. Any help would be appreciated. Thanks
