Fail to run an experiment using JEDI-SOCA

Is there anyone got similar error messages like me:

  File "venv/bin/", line 7, in <module>
    exec(compile(, __file__, 'exec'))
  File "jedi-bundle/ewok/src/ewok/bin/", line 49, in <module>
    experiment = ewok.Experiment(expconfig, suite, model, workflow, testexp)
  File "jedi-bundle/ewok/src/ewok/", line 36, in __init__
    final = suite.define_suite(self, self.config, model)
  File "jedi-bundle/ewok/src/ewok/suites/", line 72, in define_suite
    bg = suite.addTask(model.getBackground, config, fc=savefc)
  File "jedi-bundle/ewok/src/ewok/", line 51, in addTask
    tt = task(config, self.stackdirs[-1], **inputs)  # can change taskid
  File "jedi-bundle/ewok/src/ewok/tasks/", line 56, in __init__
    self.setup(config, **inputs)  # implemented in concrete class
TypeError: setup() missing 1 required positional argument: 'fix'

Any idea how I can make it happy?

Please verify that you have checked out the correct branches as specified here:

You should not be using develop branches for anything.
This problem popped up recently, which makes me think you are not using the correct skylab-v3 branches
