Elevator 4.0 incorrectly issues error that labels is required property for Indicator

[CyberDaedalus00]

In accordance with STIX 2.1 CS03, the labels property is optional on all SDO's, including Indicator. Elevator 4.0 incorrectly issues an error that states that labels is a required property

[X] indicator--de6032df-6b15-4412-8405-7e8b5dc8639f: 'labels' is a required property

Hi Chris - I think this is a validator issue...

@CyberDaedalus00 This and your other issue indicate that your elevator is using STIX 2.0 instead of 2.1. There seems to be a bug with the elevator when using it as a Python library, where it will default to 2.0. If you use the elevator's CLI script it should default to 2.1 and not give these errors. If using the elevator as a Python library you can set the STIX version using the following code from the readme:

from stix2elevator.options import initialize_options, set_option_value

initialize_options()
set_option_value("spec_version", "2.1")

In the meantime we'll work to fix the bug.

my python script looks just like what you posted, so perhaps there is another issue

@CyberDaedalus00

can you send us the script??

@CyberDaedalus00,

So here is what I think happened. The default value for the spec_version was 2.0. This caused the validator version to be 2.0 (see line 195 in options.py). The spec_version was then set to 2.1, my assumption is that there was no label, or because it generated 2.1, it used the indicator_types property instead.

We are generating a patch version of the elevator, fixing the default_value, but you might use initialize_options to set the options - for instance:

initialize_options(options={"spec_version": "2.1"})

that worked
