Look in Task Manager to see if this is the case. You can get that error when the object is attached to one exe and you try to spy an element that belongs to another exe. Often the solution is to create multiple objects, one for each exe.

I use BP 6.02.   Wed, 21 Mar 2018 17:35:00 GMT https://community.blueprism.com/t5/Product-Forum/Error-quot-There-was-an-error-during-the-spying-operation-quot/m-p/65327#M17944 Anonymous 2018-03-21T17:35:00Z https://community.blueprism.com/t5/Product-Forum/Error-quot-There-was-an-error-during-the-spying-operation-quot/m-p/65328#M17945 Hi Davide - if you're using Adobe it could be that there is more than 1 Adobe exe running.
