Confusing error message when missing a field

[Thomas Herve]

I tried to create an event alarm this way:
client.alarm.create({'type': 'event', 'event_rule': {'event_type': 'compute'}})

Aodh returned me this:

aodhclient.exceptions.BadRequest: Invalid input for field/attribute name. Value: 'None'. Mandatory field missing. (HTTP 400)

It would be much more helpful if I actually had the field name. I suspect it's query in that case.

Oh, the field *is* name... It's still confusing, but less so. Let's call it monday.

[Julien Danjou (jdanjou)]

You're right we should put quote around the field name.

should probably target wsme which is generating string.
