Hi Andrea,
which version of oTree are you running? Get it with the command:
otree --version

Can you also post your room config from settings.py, please?

Best
Christian

Hi Christian,

the version is 5.10.4, but the code was written for the 2.5.5 version. 

Here's the room config:

ROOMS = [
dict(
    name='Prolific_1',
    display_name='Prolific_1',
    use_secure_urls=False
),
dict(
    name='Prolific_2',
    display_name='Prolific_2',
    use_secure_urls=False
),
dict(
    name='Prolific_3',
    display_name='Prolific_3',
    use_secure_urls=False
),
dict(
    name='SONA_1',
    display_name='SONA_1',
    use_secure_urls=False
),
dict(
    name='SONA_2',
    display_name='SONA_2',
    use_secure_urls=False
),
dict(
    name='SONA_3',
    display_name='SONA_3',
    use_secure_urls=False
),
dict(
    name='BELSS',
    display_name='BELSS',
    participant_label_file='_rooms/belss.txt',
    use_secure_urls=True
),
dict(
    name='30463',
    display_name='Intro to Cognitive Science',
    use_secure_urls=False
),
dict(
    name='live_demo',
    display_name='Room for Live Demo (No Participant Labels)',
)
]

Thank you!

As you can see in the last lines of the logs, the argument 'use_secure_urls' is not expected when you use a Room without participant labels:

File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/otree/room.py", line 128, in get_room_dict
    room_object = NoLabelRoom(**room)
TypeError: __init__() got an unexpected keyword argument 'use_secure_urls'

For a room as the following:
dict(
    name='30463',
    display_name='Intro to Cognitive Science',
    use_secure_urls=False
)

that argument should be removed.
See also the official documentation on this:
https://otree.readthedocs.io/en/latest/rooms.html#use-secure-urls-optional

Remove the "use_secure_urls=False" statements from your room configs and it should work.


There might be a slight inconsistency in the advice oTree gives:
If you set use_secure_urls to True, but do not provide a participant_label_file, it tells you to:
"ValueError: Room "econ": you must either set participant_label_file, or set use_secure_urls=False"

If you then set use_secure_urls to False, you get the error you are seeing. So the advice is not quite right.

Thank you, it worked!!
