how to set Logarithmic increment in DAMASK 3.0.2 version

[chenbowen2019-rgb]

Dear Damask team, I am currently attempting to use the nonlocal model of Damask and plan to adopt the logarithmic incremental step to enhance the solving efficiency and convergence. However, when I input "log N: 3000", the system output an error message indicating that "│ incomplete loadcase N missing ". Could you please tell me if Damask 3 cannot adopt the keyword "log" to set the logarithmic load step as Damask 2 does? My load file is as follows:
loadstep:

• boundary_conditions:
  mechanical:
  dot_F: [[6e-4, 0, 0],
  [0, x, 0],
  [0, 0, x]]
  P: [[x, x, x],
  [x, 0, x],
  [x, x, 0]]
  discretization:
  t: 50
  log N: 3000
  f_out: 50

i am so ergent waitting for your feedback and thanks a lot for your help.
