`scripthash` not correct

[Ljzn]

Get atomicals at location returns wrong scripthash.

request:

curl -v "https://ep.atomicalneutron.com/proxy/blockchain.atomicals.at_location?params=\[%22d21f8ea708b21608b09cfec7ca263e35d69b63e1380db0f68954a2b5b3ba8c8fi0%22\]"

response:

{"success":true,"response":{"location_info":{"location":"d21f8ea708b21608b09cfec7ca263e35d69b63e1380db0f68954a2b5b3ba8c8fi0","txid":"d21f8ea708b21608b09cfec7ca263e35d69b63e1380db0f68954a2b5b3ba8c8f","index":0,"scripthash":"4b2ff9b90f0fca6341f6cac374d414a7ee59379a528990cf3a8d1c74bfa4ef45","script":"0014fb7454e043913f46cee06143ff3f320b6e2f8041","value":546},"atomicals":[{"atomical_id":"9125f03bcf9325f6071762b9aee00b461a0b43ed157c336e2e89e07f47ea6f66i0","atomical_number":149087,"atomical_ref":"j4jz0eyfjcjzc1rqcawtxr0b8rd0pgzd2ny36vheh7g7yhzadxk0i0","type":"FT"}]}}

The scripthash here is "4b2ff9b90f0fca6341f6cac374d414a7ee59379a528990cf3a8d1c74bfa4ef45" .

Not equal to the correct scripthash of address "bc1qld69fczrjyl5dnhqv9pl70ejpdhzlqzpu0mfjh", which should be "8e6cec514958b4af4002f0c0a6f9f7b0a84944fcb7e6034083c112aaf7dea721".

We can get the atomical with the correct scripthash:

curl -v "https://ep.atomicalneutron.com/proxy/blockchain.atomicals.listscripthash?params=\[%228e6cec514958b4af4002f0c0a6f9f7b0a84944fcb7e6034083c112aaf7dea721%22\]"
# response is too large to paste here

curl -v "https://ep.atomicalneutron.com/proxy/blockchain.atomicals.listscripthash?params=\[%224b2ff9b90f0fca6341f6cac374d414a7ee59379a528990cf3a8d1c74bfa4ef45%22\]"
# request with wrong scripthash just returns empty utxos

So I think the scripthash in the response of blockchain.atomicals.at_location is not correct. The script field is correct.

For convenience to others, the result of that python script is:

Is runhash_to_hex_str for scripthash on purpose here? I don't quite understand.

Hexadecimal strings are more human-readable and easier to understand.

Is runhash_to_hex_str for scripthash on purpose here? I don't quite understand.这里是故意的吗 hash_to_hex_str scripthash ？我不太明白。

Hexadecimal strings are more human-readable and easier to understand.

Yes, but the scripthash be converted to hex twice here.
