Problem with declaring sample contract to starknet testnet - starknet

Question

I'm trying to declare the sample contract as defined here:
https://www.cairo-lang.org/docs/hello_starknet/intro.html#declare-contract
When invoking the
starknet declare --contract contract_compiled.json
I'm still getting:
Got BadRequest while trying to access https://alpha4.starknet.io/feeder_gateway/simulate_transaction?blockNumber=pending. Status code: 500; text: {"code": "StarknetErrorCode.UNINITIALIZED_CONTRACT", "message": "Requested contract address [redacted] is not deployed."}.
Traceback (most recent call last):
File "/Users/[redacted]/cairo_venv/lib/python3.9/site-packages/services/external_api/client.py", line 117, in _send_request
raise BadRequest(status_code=response.status, text=text)
services.external_api.client.BadRequest: HTTP error ocurred. Status: 500. Text: {"code": "StarknetErrorCode.UNINITIALIZED_CONTRACT", "message": "Requested contract address [redacted] is not deployed."}
Error: BadRequest: HTTP error ocurred. Status: 500. Text: {"code": "StarknetErrorCode.UNINITIALIZED_CONTRACT", "message": "Requested contract address [redacted] is not deployed."}
I'm expecting to have that being worked :)
I've set everything as it's described in the tutorial above.

As mentionned by user amanusk, you need a funded account with some ETH in order to be able to declare contract classes.
This error happens because you either did not declare an account contract in your CLI yet, or because you haven't sent ETH on it yet, and so it is not initialized.
Make sure to:
Create an account usable with your CLI
Fund it with some ETH
Check that it appears as deployed in an explorer
