Hi,

 

When try any of the following get error using power platform dataflows

 

 

1)   When try set new link to data lake and choose our storage account such that results of dataflow are stored in our storage account get error below.

 

 

does not have authorization to perform action 'Microsoft.Authorization/roleAssignments/write' over scope '/subscriptions/<guid>/resourceGroups/rg-adw-dev-001/providers/Microsoft.Storage/storageAccounts/dlsadwdev001/providers/Microsoft.Authorization/roleAssignments/<guid>' or the scope is invalid. If access was recently granted, please refresh your credentials."}

 

2) When publish a dataflow get message when it tries to refresh get error below.

 

Gateway proxy unable to connect to Data Lake (host: '<mshost>.dfs.core.windows.net'). Learn how to troubleshoot this connectivity issue here: https://learn.microsoft.com/data-integration/gateway/service-gateway-tshoot#gateway-proxy-unable-to-connect-to-managed-data-lake. (Request ID: <guid>).

 

Can build dataflow and see the data  and publishes succesfully (uses vnet data gateway and azure sql database).

 

How can we create power platform dataflow which refreshes successfully using vnet gateway and azure sql database.

 

Can use power bi datasets o.k. with vnet data gateway and azure sql database but looking to also to use power platform dataflows 

 

Thanks

    Is your Datalake associated with an Azure Subscription? The error suggest that the account used to refresh the dataflow doesn't have the right level of access to the DataLake resource in Azure.
