WD0080 error in log I don't understand

I have a Studio site that is generally running OK but I am trying to debug some rogue behavior, which I don’t need help with here but I see the following also, and I am trying to determine whether I need to worry about it:

I see this error (obviously the id changes) in the logs, sometimes as much as 10 times a day. This is from Google Cloud logs for the site:

}

I am actually not querying “Members/PrivateMembersData” directly on this site at all…so I assume that an API call queryMembers(options) (in wix-members.v2) is what is causing it. I have added some console.log commands where this is used, to see if it turns up in the log next to the error next time…but I suspect it won’t.

Obviously, if I were calling this collection, then I would not be referring to updateddate (which doesn’t appear anywhere in my code for the site either), I’d be using _updatedDate.

Can anyone help me understand what is happening here? Can anyone at Wix use the info above to diagnose what is occuring - I am assuming an API call is broken at this point but I can’t tell if it’s actually a problem on my site or not.

I cannot force this to happen by browsing the site, logging in or any other activity…so I am confused but really use some help. If anyone has any ideas, I’d be glad to hear them.

Simon.

Same.

Facing similar issue on one of my sites that shows queries to Members/PrivateData spike and fail drastically but I’m never querying that collection anywhere so I’m assuming its an issue at Wix’s end.

It does appear to be a genuine failed Wix Members read, potentially caused by Wix’s deprecated PrivateMembersData adapter, so it is worth raising with Wix using the operation IDs.

@noahlovell can this be passed on to the team to investigate ?

Thanks Dan - appreciate the time taken to look at this and your elevation.
