When I run the plugin I get an error Box that says sth like: "Unknown script-error. Expression not closed - ")" missing.
+ ... andard'; .Save();
+ ~
An expression was expected after '('.
+ CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordEx
ception
+ FullyQualifiedErrorId : ExpectedExpression". Weitere Informationen finden Sie im Standardfehlerprotokoll "C:\Windows\TEMP\gce_stderrord07b04547c74493caa6bdba9087df444.log".
But I can't find the error in my code since it worked when typed manually into the powershell on the host and .Save() takes no arguments. Do you have any idea?
