Service Api (4.2.1) - Unable to access catalog



I am trying to access the entries and nodes of our catalog but get the error below. The endpoints not related to the catalog work just fine.

Any advice ?

It sounds like you need to add wildcard host name to your site definition

Thanks, but can you be a bit more specific ?

Basically this

I guess it is a screenshot but the link is broken.

Hmm, it worked for me. Please try again now

Quan, I don't see a screenshot or a link either.

Dạmn.. It seems the file is ok for a while then it was deleted. Will check with World team tomorrow. On phone, can't really do anything now

@David: Sorry for the confusion, here's how to add the wildcard hostname

Thanks, it worked!

I already had the wildcard set for my web site. The only difference was that the culture was set on the wilcard but not on the hostname. I added the culture on both, then it worked.
