Abstract: A device, system and method for resolving errors between a client device, an intermediation server and a provider system. An error-resolving computing device, receives an error indication indicative of a type of an error between an intermediation server and a provider system, the error occurring in conjunction with the intermediation server acting as an intermediary between a client device and the provider system. The error-resolving computing device retrieves, from a memory, code associated with the type of the error, the code comprising one or more of programming code and machine learning code, which, when executed, instructs the error-resolving computing device to respond to the type of the error. The error-resolving computing device executes the code to respond to the type of the error. The error-resolving computing device provides, to the intermediation server, one or more status indications indicative of a state of responding to the error.
