report fails to deploy "Invalid data source reference"

[timabell]

sanitized error:

Invalid data source reference 'SomeDataSource' in SomeReport.rdl
At C:\repo\ssrs-powershell-deploy\Deploy-SSRSProject.ps1:274 char:6

    + FullyQualifiedErrorId : Invalid data source reference 'SomeDataSource' in SomeReport.rdl

the shared dataset & datasource it relies on has already been deployed

[timabell]

this report has a direct reference to the main DataSource of the project

nothing to do with shared datasets, breaks even if there aren't any.

well that's odd, stepping through on the first run the return value from New-SSRSDataSource seems messed up during the return

https://github.com/timabell/ssrs-powershell-deploy/blob/6c7468a735fd6d35fff2cb0b536cbb1065f1b2b3/Deploy-SSRSProject.ps1#L145

inspecting within the function gives

$DataSource = @{Name=GLiMR; Path=/GLiMR Reports/FtT Tax/Data Sources/GLiMR}

but when the return is assigned to a powershell variable it's suddenly:

$DataSource = System.Object[]
> [0] = SSRS.ReportingService2010.CatalogItem
> [1] = @{Name=GLiMR; Path=/GLiMR Reports/FtT Tax/Data Sources/GLiMR}
