DataSource to PBI report fails after republishing to reporting Service

When I rePublish a Power BI report to our on-premise reporting service, the data source needs to be reset.

We have Reporting Service (May 2022) and setting up deployment using Powershell. My test report is already deployed to the service, the data source has been setup and a subscription created to run daily. Created a powershell script, using the Powershell function PublishPBIXFile.ps1 (changed the script slightly to not overwrite the data source) , to deploy all SSRS and PowerBI reports to the appropriate server.

When I republish the PBI report , I select 'manage','data sources' and all looks fine until I select 'test connection' where it fails. Also noticed that the subscription has disapeared! When I re-enter the password for the data source, connection tests sucessfully and the subscription re-appears ! 

Even tried it with the overwrite option , but the same issue occurs

Resolved by changing the OR statement to check if the password was set ....

if ($Credential -or $username) {
    if ($Credential) {
        $UserName = $Credential.UserName

Changed it to :

if ($Credential -or $secret) {
    if ($Credential) {
        $UserName = $Credential.UserName

 

Didnt care about the connection type as we would always uyse the same type

Hi @MrMGoo ,

 

Could you provide the relevant powershell code, as I am unable to reproduce your problem at the moment.
Also you can refer to the following similar solution, if it helps you.

 

Powershell - Test-Connection failed due to lack of resources


If the problem is still not resolved, please provide detailed error information and let me know immediately. Looking forward to your reply.


Best Regards,
Henry

Hi Henry,

I seem to loose all my indents when I copy the code but hopefully you can read it. I can confirm the parameters are populated as I placed a load of write-output statements in publishPBix script. Discovered that it does not get to set $Password to $secret , so dont know if I'm passing enough parameters !

 

 

The code I use to call PublichPBIxFile is:

. "C:\Program Files\WindowsPowerShell\Scripts\publishpbixfile\1.0.0.2\PublishPBIXFile.ps1"

$publishPBIXFileSplat = @{
ReportServerURI = $ReportServerURI
folderLocation = $folderLocation
description = $description
pbixfile = $objectFullPath
folderName = $deployFolderName
AuthenticationType = 'Windows'
ConnectionUserName = $ConnStringUser
Secret = $ConnStringPwd
Verbose = $true
Overwrite = 'Y'
}
Publish-PBIXFile @publishPBIXFileSplat

The code for PublichPBIxFile is:


function Publish-PBIXFile {
[CmdletBinding(DefaultParameterSetName = 'ByUserName', SupportsShouldProcess)]
Param(
[Parameter(Mandatory = $true)]
[string]$FolderName,
[Parameter(Mandatory = $true)]
