Can you confirm that the board you selected in the Arduino IDE is the Uno board and not the ESP. Also, make sure you have the comport selected for the Uno board. Looks like COM5 isn't it.
Then as @cassio.lucass states, you need to make sure the RX line on your Uno is disconnected from the ESP shield otherwise you have your PC and the ESP fighting over who gets to talk to your Uno.
Next if all that works and your Uno programs, but you are not connected to Cayenne, please confirm that your ESP is programmed with AT firmware and that it is a newer version.
