Including schema in ice.png

For data modelers & consumers
1

When I do a http GET to the ice.png and then later choose to enrich it, the enricher does not recognize the event.This is the error from the enricher:

"errors":[{"level":"error","message":"Unrecognized event [null]"}],"failure_tstamp":"2016-12-20T08:05:45.060Z"}

How do I add a schema to a ice.png request?
I have tried adding a schema=iglu:com.snowplowanalytics.snowplow/unstruct_event/jsonschema/1-0-0 query string, but still the enricher does not recognize the event.

My full event to ice.png is:

/ice.png?data=champion&schema=iglu:com.snowplowanalytics.snowplow/unstruct_event/jsonschema/1-0-0

Hi @khebbie - where did you get this syntax from:

/ice.png?data=champion&schema=iglu:com.snowplowanalytics.snowplow/unstruct_event/jsonschema/1-0-0

I don’t recognise it from either the Snowplow Tracker Protocol, the Iglu Webhook Adapter or the Pixel Tracker.

Thank you for the pointers.
I simply looked through the source code and found examples in test.
But this page https://github.com/snowplow/snowplow/wiki/pixel-tracker helped a lot.
