print a json representation of the error response. Also i changed the name of the file to follow naming convention

With this update i can persist the switch values for the different operators using the modal and the useTransactionHistory Hook.

default value for quick login (doesn't show on the screen put pressing the button will send those values in the request).
Will be removed.
