When I reviewed the dependencies that VBO is not listed yet the process is still looking for the VBO mention. That VBO was deleted and recreated with a new name. What could be the cause and how we resolve it.   Thank you Chris Fri, 07 Sep 2018 19:39:00 GMT https://community.blueprism.com/t5/Product-Forum/Failed-to-create-session-on-C1W-BPDRR01-Failed-to-get-effective/m-p/80682#M32368 ChiragSurati 2018-09-07T19:39:00Z Chris, any resolution with… https://community.blueprism.com/t5/Product-Forum/Failed-to-create-session-on-C1W-BPDRR01-Failed-to-get-effective/m-p/80683#M32369 Chris, any resolution with this?
