The microflow error states that you do not have the input parameters available on the page that you are triggering the microflow from. Maybe create a microflow with the parameter(s) you do have and then from that microflow trigger the microflow that triggers the error. You do need to implement the logic to fill these parameters though.
Be aware that before mendix 10.12 primitive parameters like string, int etc. where not avaiable for th use in in microflows parameters when calling the microflow from a page, only objects can be passed directly.
