Power BI API bug: request is incorrectly returning no upstream datasets

[LuizBudeu]

The API endpoint for "Get Datasets In Group" (https://learn.microsoft.com/en-us/rest/api/power-bi/datasets/get-datasets-in-group) is returning that my dataset has no upstream datasets (it is returning "upstreamDatasets": []), when the dataset actually has upstream datasets, clearly visible in the lineage of a report that uses this dataset.
Fortunately, when I opened up the Network tab when the Power BI report was loading, the GET request to "https://wabi-south-central-us-redirect.analysis.windows.net/metadata/appmodel/apps/{worspaceId}?requ... had the ids of the datasets that the dataset of this report depended on. This is obvioulsy a hack, and the upstream datasets should be mentioned in the proper API endpoint.

Hi @LuizBudeu ,

Based on the above information, this issue may need to collect log files for further troubleshooting. Since community support engineers don't have that access, I would suggest opening a Support Ticket. If you are a Power BI Pro or Fabric licensee, you can create a support ticket for free and a dedicated Microsoft engineer will come to solve the problem for you. 
It would be great if you continue to share in this issue to help others with similar problems after you know the root cause or solution.
