Pygsheets update_cells() not working

Question

I am trying to update a range of 3 cells horizontally using pygsheets but I am having some issues

The Error:

Traceback (most recent call last):
  File "C:\Users\Art\Desktop\Python\Plain\General_testing.py", line 12, in <module>
    wks.update_cells('I{0}:K{0}'.format(rows),[output['Name'], output['Age'], output['State']])

Invalid value at 'data.values[1]' (type.googleapis.com/google.protobuf.ListValue), "19"

Simplified version of my code that produces the same error:

import pygsheets

gc = pygsheets.authorize(service_file='secret.json')
sh = gc.open('TestSheet')
wks = sh.sheet1

row = 1
output = {}
output['Name'] = 'Joe'
output['Age'] = '19'
output['State'] = 'NY'
wks.update_cells('I{0}:K{0}'.format(row),[output['Name'], output['Age'], output['State']])

Answer 1

The update cells take a 2D matrix (list of list) as input for values not a list

wks.update_cells('I{0}:K{0}'.format(row),[[output['Name'], output['Age'], output['State']] ] )
