 Hi Ravi,As informed you before, please verify the NSO documentation provided in the NSO installation folder. They provide API's as well.You should be able to debug using these resources.We did not face this error in TSDN CFP, so we would not know the cause. ThanksSahithiQuery is for the NSO platform team.
