Tried adding different numbers but received the code in none

I tried to test Deferred Deep Link using the App ads helper, but "Deep link notification could not be sent due to some error" An error occurs.
error : 1357031
errorDescription : "The content you requested cannot be displayed right now. It may be temporarily unavailable, the link you clicked on may have expired, or you may not have permission to view this page."
errorSummary : "This content is no longer available"

We're encountering a scenario where a Primary Business Page is aggregating a subset of Store Location Pages' website URLs.
We can't seem to find any documentation regarding this from the Page API Reference (e.g. https://developers.facebook.com/docs/graph-api/reference/page/) and was hoping to reach out to see if anyone else had come across this situation, and resolved it.
For clarification, not ALL Store Location Page website URLs are appearing, only a small subset. We were hoping to only have the first website URL appearing.
We were originally noticing it occurring when updating a Store Location; however, it does not happen consistently across all Store Location Page updates.

I understand that from V22.0, instagram story_insights will change from impressions to views, but when will views be added to the webhook?
