In QueryEntity, we are using nested condition to get the desired data from the DB Table. However, we are getting "Expression evaluation error at function a!queryEntity: Cannot apply a filter with a blank field name." exception during execution. Without the nested condition the query works fine and when we introduce nested condition, we are getting the mentioned error. We couldnt figureout what went wrong. Any help is appreciated. Please find the queryEntity rule attached for reference
