Going by your question I will assume you are trying to get the transaction history of your wallet? The endpoint you are using requires an address previously associated with a transaction, and an unused receiving address won't return anything.

Your wallet consists of multiple UTxOs across multiple addresses, and that information is persisted locally by the wallet software so it's easy to obtain details like the transaction history. However in the context of statelessly querying Blockfrost you will have to retrieve all these addresses using the [Account associated addresses
endpoint](https://docs.blockfrost.io/#tag/Cardano-Accounts/paths/%7E1accounts%7E1%7Bstake_address%7D%7E1addresses/get) and then query the transactions per address. It might be a little easier using the [Koios API because the resource takes an array of addresses](https://api.koios.rest/#post-/address_txs) but there is no easy way to achieve what you want at the moment.
