Refactor Fields using PyQGIS3

Question

I am trying to use Processing tool to automate refactoring for several tables: here is the code I am trying to use

import processing
input = 'C:\\Users\\Ehsan\\Desktop\\CIS WORK\\Sample 
files\\GeoJason\\cable.geojson'
output = 'C:\\Users\\Ehsan\\Desktop\\CIS WORK\\Temp\\'+'cable'+'.geojson'

processing.run("qgis:refactorfields",
                  input,
                  [{'name': 'id',
                    'type': 10,
                    'length': 10,
                    'precision': 0,
                    'expression': 'Value'
                   }],
                  output)   

When I run this program I get the following error:

Traceback (most recent call last):
