When a newly created market order is ot filled (e.g. according to app has status "Cancelled"), the response object is totally useless.
It does not tell what the issue was, why the order got cancelled by the system, nothing.
Instead, the response contains basic info like
(
<lighter.transactions.create_order.CreateOrder object at 0x000001FFFFFFFFFF>,
RespSendTx(
code=200,
message='{"ratelimit": "didn\'t use volume quota"}',
tx_hash='1234567890abcdefg1234567890abcdefg1234567890abcdefg1234567890abcdefg1234567890ab',
predicted_execution_time_ms=1773418001481,
volume_quota_remaining=None, additional_properties={}
),
None
)
So unless there is a parameter error (which the class tells you during development), when the order does not succeed, please implement information on why exactly it did not get filled but randomly cancelled, in the response object.
