Sentry API permalink field always null

I have noticed recently that the “permalink” field that used to link to the specific page on the sentry site is always null. I’m certain it used to be populated because I have sentry reporting tool I wrote that used that field to link report viewers to sentry.

Searching the documentation, all current API examples have this field as “null”:
https://docs.sentry.io/search/?q=permalink

Is this field being deprecated? Should I just be manually building links to sentry?

Thanks!
