[UWP] Getting Unknown DisplayCatalogError from Query for Product

Hi,

We have been using UWP collections query API (which is explained in this document: https://docs.microsoft.com/en-us/windows/uwp/monetize/query-for-products), and recently, we're intermittently getting unknown errors from it.

I think the error response is not originating from our end, these are the reason.
- we are using the same code & configuration on calling the API for over a year but started to receive this kind of error message only since about two weeks ago.
- I've made a test script that repeatedly calls the API with the interval of 0.5 seconds, with the same request bodies and Azure AD token. It mostly returned a normal response, but occasionally (about 1 out of 20 requests) returned an error.


And here is the full (inner) error message (body.innererror)

{
"code": "EntitlementsError",
"data": [
"DisplayCatalogError",
"An unknown error has occurred when calling DisplayCatalog.",
"An unknown error occured."
],
"details": [],
"message": "Collections received an error from entitlements.",
"source": "CollectionsFD"
}

I've tried to find any information about this kind of error, but that didn't work.
Could you help us to find the cause of this issue?

Thanks!

Chung

As you mentioned that the code works before over a year, have you changed your code recently? Is the still the same code that used to run correctly?

What I've meant was, we have not changed any of our code and configuration in over a year. So it's the same code we're using now and then.

You mentioned that you've created a script to call this request and it works, so only in your app that you are getting the unknown error, right?
