Date filtering does not work

[sasi]

A working post without date filtering:
{"jsonrpc":"2.0","method":"SportsAPING/v1.0/listMarketCatalogue","id":"1","params":{"filter":{ "eventTypeIds":["2"],"marketTypeCodes":["MATCH_ODDS"]},"maxResults":1000}}

The same post with just the date filter added, does not work:
{"jsonrpc":"2.0","method":"SportsAPING/v1.0/listMarketCatalogue","id":"1","params":{"filter":{ "eventTypeIds":["2"],"marketTypeCodes":["MATCH_ODDS"],"marketStartTime":{"from":"Jun 25, 2021","to":"Jun 29, 2021"}},"maxResults":1000}}

Reponse: {"jsonrpc":"2.0","error":{"code":-32602,"message":"DSC-0018"},"id":"1"}

The API reference says: DSC-0018 MandatoryNotDefined - A parameter marked as mandatory was not provided

Though I have no idea which parameter is missing, my TimeRange class has the same fields as described in the API reference guide. If I paste the text into a JSON validator it shows no problem. Any help would be appreciated.

Edit:

After some searching in the forum, I've managed to find out the solution. I was missing to include the hour min secs in the data. For example: marketStartTime":{"from":"2021-06-26T14:28:44.127Z","to":"2021-06-29T17:28:44.131Z"}

Now it's working as expected.

The marketStartTime is stored as a timestamp. There are examples of calls using the appropriate time format in the Getting Started section of the documentation.

Thank you for replying, it seems it also works with date-time, not with date only though.
