Cannot nake proper marketFilter to subscribe markets

[1hor]

When trying to subscribe markets I specify market types (WIN and PLACE) and date range (today's only)
but getting an error that i tried to subscribe 18 000 markets

could someone tell where i made mistake?
{"op":"marketSubscription","id":6,"marketFilter":{ "textQuery":null,"exchangeIds":null,"eventTypeIds" :null,"eventIds":null,"competitionIds":null,"marke tIds":null,"venues":null,"bspOnly":null,"turnInPla yEnabled":null,"inPlayOnly":true,"marketBettingTyp es":null,"marketCountries":["GB","IE"],"marketTypeCodes":["WIN","PLACE"],"marketStartTime":{"from":"2019-09-20T11:34:05.3535344+02:00","to":"2019-09-21T00:00:00+02:00"},"withOrders":null}}

The way to solve a programming problem like this to simplify your code until you find the part that is failing.

Have a look here
https://docs.developer.betfair.com/d...riptionMessage
then scroll down to Market Filtering/MarketFilter and check your parameters. Several of them do not match what is specified.

You shouldn't need to use Null for parameters you're not specifying. Omit those.
