PowerShell get-gateways always returns blank value

Hi v-jiascu-msft, thanks for the reply.

Yes, I want the data from the link you specified - as well as the information from its parent, the gateways.

I am using Invoke-PowerBIRestMethod successfully to retrieve workspaces, dashboards, dashboard tiles, reports, datasets, dataset gateways, dataset datasources and dataset refreshes. All of these invocations work correctly and return the data on my objects.

However, when I use "Invoke-PowerBIRestMethod -Url 'gateways' -Method Get" it returns an empty value - there are no gateways returned. So of course, that doesn't give me any gatewayids to use to get the datasources.

Funny thing is, when I use Invoke-PowerBIRestMethod where the Url contains "datasets/<datasetid>/gateways" I get the gateway each dataset connects to, and when I specify "datasets/<datasetid>/datasources" I get the datasource for each dataset.

But in this workspace those give me the same gateway on every dataset, and the same datasource on every dataset. What I want is a simple list of distinct gateways and distinct datasources, but those commands don't return anything.

By the way I am logging in as the Power BI Global Admin for the tenant, so all data should be available to me, correct?

Thanks,

Sam
