Solution

Use var_dump($oFolders) to get more details about $oFolders.
Note that $oProcessor->GetFolders(); inside if(2 === $type) block don't returning any object.

OTHER TIPS

It simple means as in error message that variable $oFolders is not an object that has GetFolderByType method. You should check your code and look what is $oFolders
