The VideoForwardingError exception occurs when a client who uses the 7.0 or earlier version of the MCU tries to use the VideoForwarding feature. Video forwarding is available only for clients who use the 7.1 or later version of the MCU. The VideoForwardingError exception also occurs when a client provides an incorrect value of the max parameter. The valid parameter's values are between 0 and 25 for desktop browsers and between 0 and 4 for mobile browsers. In the case of providing a value smaller than 0 or greater than the valid values, SDK triggers the error.
