I am trying to get the Fermentrack up and running. I just applied power to my "
Makerfocus D1 Mini NodeMcu 4M Bytes Lua WiFi Development Board Base on ESP8266 ESP-12F N Compatible NodeMcu Arduino (D1 Mini)
purchased from Amazon.

I am following the GUIDED DEVICE SETUP IN Fermentrack and I get the following error when it begins to flash.
TypeError at /firmware/flash/6/
__init__() got an unexpected keyword argument 'max_errors'

Steps 1 , 2 and 3 were ok and in the Select Firmware To Flash screen I have " Serial Port/dev/ttyUSB0Device FamilyESP8266BoardNodeMCU (ESP-12E)"

I then select " BrewPi/w WiFI" "Flash to Device" and thats where I get that error.

Can anyone help.
