Change data source connection strings in Power BI reports with PowerShell

[castrom]

Hi,

I'm trying to automate PowerBI reports deployment using Azure Pipelines and PowerShell.

I am able to connect to PowerBI using Connect-PowerBIServiceAccount and a service principal.

I also can list workspaces and existing reports.

My next task is to change the data source connections. I have been following this MS documentation https://learn.microsoft.com/en-us/power-bi/report-server/connect-data-source-apis but when I try the following:

# Get report parameters

$parameters = Get-RsRestItemDataModelParameters '/Infusion_Model_Auto'

I get this error:

Failed to create a new session to http://localhost/reports/api/v2.0/me :

| The cmdlet cannot protect plain text secrets sent over unencrypted

| connections. To suppress this warning and send plain text secrets over

| unencrypted networks, reissue the command specifying the

| AllowUnencryptedAuthentication parameter.

I'm not sure what's going on, since I already have an active connection.

Thanks for any help.

Hello,@castrom .I am glad to help you.
It looks like you are trying to implement a report data source change on Power BI Service (not Report Server)
Hopefully the following API link will help you out

Gateways - Update Datasource - REST API (Power BI Power BI REST APIs) | Microsoft Learn
 

I hope my suggestions give you good ideas, if you have any more questions, please clarify in a follow-up reply.

Hi @lbendlin ,

I think I just realised that the instructions here are for a PowerBI on prem setup.
We are using the PowerBI app in Azure, so I don't think we have a PowerBI Reports Server.
I will try another approach now, by using the PowerBI Rest APIs.

Thanks for coming back to me though.

Please confirm if you indeed are attempting to do this for Power BI Report Server.
