transaction – help with serializing dictionary digest for txid calculation

I tried serializing the transaction for txid calculation and got this predigest:

 01000000      // version
 01            // input count
 a6026e772ab727c8619986490fceaa5a072344ebe2b9d666deb1d8de72083cb3 // outpoint.txid
 01000000      // outpoint.index
 00            // scriptSig length
 fdffffff     // sequence
 02           // output count
 b49cac0000000000   // output.value
 16          // scriptPubKey length
 00146158eebd1aec7512fc33e9cfb95f388fd3a62617   // scriptPubKey
 b01f480600000000   // output.value
 16          // scriptPubKey length
 0014373f3051c8c409bf1e12ddb2bd4165c7c0ef9310 // scriptPubKey
 00000000    // locktime

Raw: 0100000001a6026e772ab727c8619986490fceaa5a072344ebe2b9d666deb1d8de72083cb30100000000fdffffff02b49cac00000000001600146158eebd1aec7512fc33e9cfb95f388fd3a62617b01f480600000000160014373f3051c8c409bf1e12ddb2bd4165c7c0ef931000000000

This is the deal.

I tried to explain the change in endianness and got this txid (how it shows up in cli):

698675daa46546737422856fe2eb81fcb4740eb19d1f4cf7837c27603c9f9ce7

But the correct txid is:

fff53b0fda0ab690ddaa23c84536e0d364a736bb93137a76ebf5d78f57cdd32f
