For tasks it’s
"permalink_url": "https://app.asana.com/0/{some_id}/{task_gid}",
and it works fine.
However for projects I receive:
"permalink_url": "https://prod/0/{project_gid}/{project_gid}",
and the link is obviously unresolvable due to the host name i.e. “prod”.
Fun fact of the day, did you know https://app.asana.com/0/0/{task_gid} always works?
Hmm, interesting. I’ve never tried constructing URLs, I always use those provided by the repository.
imho the behavior described in the first comment is clearly a bug. Is this the right place to report it?
Here is perfect I think! cc @Ross_Grambo
Hi there! Your friendly API engineer here 
This is definitely a bug - we’ve found the root cause was with some internal refactors. We’re going to turn this off ASAP which should fix this by end of day.
I’ve gotten word that it’s been fixed, and I’ve been able to confirm it myself! 
Yup, works fine now. Case closed. Thanks guys!
I’m sorry but I have to reopen this thread, it is happening again for projects. Tasks seem to be unaffected.
… and it’s fixed again. Thanks!
