Describe the bug
When retrieving a list of resources using the Azure API(https://learn.microsoft.com/en-us/rest/api/azureml/registries/list-by-subscription?view=rest-azureml-2024-04-01&tabs=HTTP#code-try-0), the number of returned resources is multiplied by the number of regions in which they are deployed. This results in duplicate entries for each unique resource across all regions.

To Reproduce
Steps to reproduce the behavior:

1. Deploy multiple registries across distinct regions.
2. Use the API to list the deployed resources (either via CLI or SDK).
3. Example:

• With 6 registries deployed across 5 regions, the API returned 30 items, with each registry duplicated 5 times.
• Similarly, deploying 5 registries across 4 distinct regions (i.e. 2 of them in the same region), returned 20 items, again duplicating the resources based on region count.

Expected behavior
The API should return a single entry per unique resource, regardless of how many regions it is deployed in.

@jojoochen ,could you share more screenshots or details？
If I create 2 Registries "A" and "B", and the Primary regions in A is westus and it's additional regions are eastus and eastus2euap, the Primary regions in B is centralus and it's additional regions are eastus and eastus2euap
and then I call the list api, the result will be 4 as there's 4 regions are deployed Registries ?

now in my resource group, I have one registry with a primary region and two additional regions. Then the result after calling the list api are 2. Does the regions in

Thank you for your response and for looking into this issue!

What I meant by region does not refer to the additional regions.

Here are the steps to reproduce the issue:

1. Using my current resources, I first created five registries, with their locations spread across four different regions—two of them are in the same region.

2. Then, I ran the API command: az ml registry list. (https://learn.microsoft.com/en-us/cli/azure/ml/registry?view=azure-cli-latest#code-try-5)

3. As a result, each registry was listed four times, returning identical entries for each.

Therefore, the total count was 5 registries * 4 identical entries = 20 resources.

I appreciate your help in resolving this and look forward to your insights. Thanks again!

I can repro this issue with using Rest Api, so I think this should be a service backend issue,
Add Service Attention for awareness

Hi @kazrael2119, thanks for your previous response regarding the issue. Since it's been a week, I wanted to kindly follow up and check on the current status.
Is there any further update on the resolution of this backend issue, or is there anything we need to do on our end.
Thank you so much!
