I get following error during initialization (Python 3.8.11).

import bitcoin_explorer as bex db = bex.BitcoinDB(r"D:\BTC\Chain")

I have data downloaded using Bitcoin Core in D:\BTC\Chain\blocks (.dat files) and D:\BTC\Chain\blocks\index (.ldb files).

I'm using the explorer in a regtest mode bitcoin-core and when I use the function "db.get_transaction()" for a specific transaction, it returns the following data:

[23:35:22] INFO - Start loading block_index
[23:35:23] INFO - Successfully opened tx_index DB!
{'txid': '4f820b821643587d0fb89720e0b2e8e32b6db4533e12c94ec1fee16b3539f7ab', 'input': ({'txid': '39a1aca5790d939d75159e43fc02c77a621c3c6119bc18fd32efee66e17b5657', 'vout': 1},), 'output': ({'value': 2000000000, 'addresses': ('bc1qjpjrryrqxykpe7x7uq63a0jfcc0upral3682a7',)}, {'value': 1999999718, 'addresses': ('bc1qxp54zryddh5jlqnd0u3cmrkt6j7eyrsq2769uu',)})}

If I check the same transaction with bitcoin-cli gettransaction I get the following data:

}

Why the data don't match? for example, doesn't appear in the return of the bitcoin explorer, or if I check the transaction that appears in the input of the bitcoin explorer ('39a1aca5790d939d75159e43fc02c77a621c3c6119bc18fd32efee66e17b5657') bitcoin-cli returns that is invalid.

Thanks for reading.
