Parameter serialization errors are hidden AND incorrect error message

[jrgns]

I was calling post_market_order but got an ErrMarketUnavailable error.

I double checked the pair value, and it was correct, but after some digging it appeared that the Content Type of the request was 0.

I noticed that this code essentially hides any serialization errors with parameters.

I found my error by running

req = {
# with all my parameters
}

print(json.loads(json.dumps(req)))

This highlighted that I was passing in a Decimal (which can't be serialized).

So, two issues:

1. ErrMarketUnavailable is sent back if you're not sending any data. Empty request (or something similar) would be a better response
2. Parameters are emptied without warning, making it difficult for the coder to understand where the issue comes from.

See case 1775940

Thanks for raising this @jrgns!

Agree that this isn't right.
We'll work on a fix shortly and add you as a reviewer.

And sorry could you confirm what the ID of 1775940 is that you shared - is that the case ID where you contacted the support team?
