aiohttp parser breaks with more than one argument

Nothing seems to work once I add more than one field. Here’s my minimal example.

I’m validating with:

programs_actions_args = {
    'type': webargs.fields.Str(required=True),
    'chain': webargs.fields.Integer(required=True),
}

and here’s what happens when I POST:

POST /v1/programs/8137474d19926b0aa8efd4f1d3944131d59269d97a7bd8dab8e79d667eb314df/actions HTTP/1.1

{
    "chain": "3",
    "type": "sampling"
}

HTTP/1.1 422 Unprocessable Entity

{
    "type": [
        "Missing data for required field."
    ]
}

Things work fine if there’s only one argument.

Just FYI: The latest release (1.6.2) includes the fix for this.

I wish I knew more about marshmallow and aiohttp internals. I’ll probably take a stab at it eventually. Thanks for webargs (and everything else)!
