Using unconfirmed utxo as input broadcast transaction failed

When constructing a transaction using this input, I get the following error:

Error: BtcAssetsAPI returned an error: (400) sendrawtransaction RPC error: {"code":-25,"message":"bad-txns-inputs-missingorspent"}

This is the input used in the transaction:

[
  {
    "hash": "e7bb86c081a833c3092df98b8ca479cf0b30308411d99a243106c2f7f84207ac",
    "index": 0,
    "sequence": 4294967295
  }
]

If the input's previous transaction was constructed in Unisat and then the second transaction is broadcasted using btc-assets-api, this error occurs:

Error: BtcAssetsAPI returned an error: (400) sendrawtransaction RPC error: {"code":-25,"message":"bad-txns-inputs-missingorspent"}

However, if both transactions are constructed entirely in Unisat or entirely using btc-assets-api, there are no issues.
