KeyError: avg_order_size, which in features_config, yet not integrated into X in processor.py, but used at Line 207?

Hi, I get KeyError while running the QuickStart steps,
Could you please help to give a hint?
Thanks!

Following shows the Pic regarding my problem,

That is to say,
At line 207, In processor.py,
According to the Quick Start, the avg_order_size is from
features_config[“features”],
features_config = {
"features": {
"avg_order_size": {"type": "N"},
...

And, I can’t see anywhere X in processor.py, which is mainly from data_frame, integrates avg_order_size into itself,
Data_Frame:

row	mdp_id	sequence_number	context	decision	reward
1	u123	1	{"country": 2, "year": 1796}	female	154.2
2	u456	1	{"country": 4, "year": 2017}	male	170.9

which makes me don't know how to fix it by making sense...

Hey @Joecth - features should match the features present in your context. See example_feature_config.json for an example.

Thanks for your reply, @econti!
Just now, I already simply replace features_config on QuickStart page with the content in example_feature_config.json, shown as the pic,

I can see the features includes country, year, and decision, which is already consistent with context in DataFrame.

However, looks like it receives an empty array in preprocess_feature() in proprocessor.py, and thus raised ValueError...

Is it possible for you to guide a quick fix regarding what happened here?
(p.s. I just wanna smoothly and successfully run it up to get more idea abt it according to QuickStart.., but still not able to... )

Thanks~!
