Description keyword does not validate properly

[jrmcmah2]

So I have the following situation. where I am trying to validate a pretty simple schema:

instrument_schema = { "cusip": { "type": "string" }, "symbol": { "type": "string" }, "description": { "type": "string" }, "exchange": { "type": "string" }, "assetType": { "type": "string", "enum": [ "EQUITY", "ETF", "FOREX", "FUTURE", "FUTURE_OPTION", "INDEX", "INDICATOR", "MUTUAL_FUND", "OPTION", "UNKNOWN" ] } }

The payload that I am looking to validate looks like this:

test_payload = { "AAPL": { "cusip": "037833100", "symbol": "AAPL", "description": "Apple Inc. - Common Stock", "exchange": "NASDAQ", "assetType": "EQUITY" } }

I am validating just like this:

jsonschema.validate(instance=test_payload, schema=instrument_schema)

When I run this, I get the following error:

The description in the test payload is clearly a string valie just like exchange or cusip. The interesting part of this is when I change the key in both the payload and schema from "description" to "descriptio" the validation works just fine. This is very weird. I would not expect a particular key value to be a problem, especially one like "description" that is so common in various json payloads. Could anyone provide guidance as to what I may be doing wrong here?

Additionally if this is not the correct place for this post I do apologize. Please let me know and I will repost in the proper spot.

You mean {"properties": everything_you_have_there}.

The error is telling you that your schema is invalid because the description validator, which is a validator in JSON Schema, requires a string, and you gave it something else, a dict, the dict {"type": "string}. But you don't mean to use that validator at all, you're trying to define a property of your instance.

Hope that helps.

Thanks for the reply! I misread the my input body and did not see that the first level of key(s) only had the single key. I wanted to evaluate the dictionary that had the key "APPL" in my input. Thanks for the help pointing that out!
