Hi Badri, Please consider to send more info during asking for help. You are opening script in JMeter 5.4 but script are saved in folder which name my suggest that it is JMeter 5.5 and You don't even attach logs. It would be easier to help when you send some context:) Regards, Mariusz On Mon, 26 Jun 2023 at 14:58, Pichkhadze, Badri <badri.pichkha...@fmr.com.invalid<mailto:badri.pichkha...@fmr.com.invalid>> wrote: Hi, Every time I open up a test I get this error anyway I can fix it?
