Get deactivated features with PnP

Question

I am trying to automatically install and activate a solution to our Project Server 2019.

I have already installed the solution with Install-PnPSolution, but I cannot activate the feature.

When I activate the feature by hand, I can use Disable-PnPFeature to deactivate the feature again. When I do the same with Enable-PnPFeature, the feature does not get activated.

I suspect that it has got something to do with the ID of the solution. When I activate the feature by hand, I can have it listed with Get-PnPFeature. In this case the GUID of the feature is not the same as during installation.

Unfortunately, I have not found a way to get a list of installed but deactivated features.

How can I get a list of the installed but deactivated features?
What else could cause the feature not being activated?

Here the code:

Connect-PnPOnline -Url $siteUrl -Credentials $cred
Install-PnPSolution -SourceFilePath $solutionPath -PackageId $solutionId
Invoke-PnPQuery
Enable-PnPFeature -Identity $solutionId

Answer 1

I got it working now.

There were two problems. The first was that the Solution ID and the Feature ID are not the same. The second that the sandbox flag was not set, although I am trying to install a sandboxed solution. After passing it the feature ID instead of the solution ID and setting the Sandboxed switch it worked like a charm.

Connect-PnPOnline -Url $siteUrl -Credentials $cred
Install-PnPSolution -SourceFilePath $solutionPath -PackageId $solutionId
Invoke-PnPQuery
Enable-PnPFeature -Identity $featureId -Sandboxed

Unfortunately, I have not found a solution to get a list of the deactivated features remotely.

The PnP command can only get activated features in the SharePoint sites, you can use Get-SPFeature command.
