I'm downloading races and runners every morning and have come across a problem today where many races are missing runner metadata.
For example Gundagai Race 7 is a valid race abd you can find it on the Betfair website to place a bet. Via the API (and confirmed again onthe Visualiser) the runners do not return when queried.
Below is the request, as per the visualiser:
"Request data:
[{"jsonrpc": "2.0", "method": "SportsAPING/v1.0/listMarketCatalogue", "params": {"filter":{"marketIds":["2.101068826"]},"maxResults":"100","marketProjection":["RUNNER_METADATA"]}, "id": 1}]"
Below is the response:
[{"jsonrpc":"2.0","result":[],"id":1}]"
Am I doing something wrong here, as it usually works for all races but today some are returning nothing?
