Microsoft.SharePoint.Client.ResourceNotFoundException type not found

Question

I am getting following error while using [https://github.com/pnp/pnpframework] and I want to specifically catch this error.
But there is no such a type 'Microsoft.SharePoint.Client.ResourceNotFoundException' , is there way to handle this error ?

{
"odata.error":{
"code":"-1,
Microsoft.SharePoint.Client.ResourceNotFoundException",
"message":{
"lang":"en-US","value":"Cannot find resource for the request
SP.RequestContext.current/web/sitecollectionappcatalog/."
}
}
}

try
{
var appMetadata = appManager.Add(filePath, true, AppCatalogScope.Site);
if (appManager.Deploy(appMetadata.Id, false, AppCatalogScope.Site)) {...}
}
catch (Exception ex)
{

}

Hi @DevAsith ,
If it fails at the Get-PnPApp step already, it most probably means you connected to a site using Connect-PnPOnline for which you have not explicitly enabled the site collection app catalog feature. Follow the steps in this document :
