The Ad link that you generate from the Branch Dashboard is a tracking link that needs to be provided to your Ad Partner, who will then use this link to create ad campaigns.
You are seeing an error when directly clicking on this link as this will not have values for the Parameters on the link. You can test this link by adding the parameters to the ad link manually.
For example, if the platform is iOS, remove AAID parameter from the link and append the device ID value for IDFA as: '%24idfa=xxxxxx'. Similarly, for Android, remove the IDFA parameter from the link and append the device id value for AAID.
