Testnet rpc end point not working correctly

[bagikh]

Hello, https://testnet.data.api.ripple.com is not working correctly. More specifically,

/v2/ledgers gives me the strage data

{
"result": "success",
"ledger": {
"account_hash": "9C4161B246E0221A0552402982A1266272CC634EDC8CAB32FEE461985342BEB1",
"close_flags": "0",
"close_time": 1566953031,
"close_time_resolution": "10",
"ledger_hash": "167AF74419312A00C26245C1A8E728C9D3F17ECD1BBD6209B19F15BCC5C17FEA",
"ledger_index": 22189035,
"parent_close_time": 1566953030,
"parent_hash": "453F005C7CAC16585F4C6277BC38A529BBC2B93880B26A5380CD33BC3DCB6607",
"total_coins": "99996928944636091",
"transaction_hash": "A9FA0DC87129A55651C0C4FADC4A4E4E42486818A3EB7342283ADA2A8FC84C5A",
"tx_count": "5",
"close_time_human": "2019-Aug-28 00:43:51"
}
}

Also, /v2/ledgers/13365671 results as :
{
"result": "error",
"message": "unable to retrieve ledger"
}

However, i checked that my transaction is included in that (13365671) through ripple testnet explorer.

Is this endpoint working or synced?? OR is there any other testnet rpc endpoint for testing /v2/ledgers and /v2/ledgers/{ledgerIndex}? Thank you.
