Hi there,

Although I succeeded bittcoinetl get_block_range_for_date command, I got following errors and failed when I run bitcoinetl export_all command.

$ bitcoinetl export_all -s 0 -e 573154 -b 100 -p http://bitcoin:local321@127.0.0.1:8332 -c bitcoin

I use Ubuntu 18.04 LTS, Python version is 3.6.8, and I got result by running bitcoin-cli getblockchaininfo

ethreum-etl is working well, by the way...

Thank you,

For some reason the bitcoin rpc expects a boolean value for the 2nd param in this request:

[{"jsonrpc": "2.0", "method": "getblock", "params": ["00000000839a8e6886ab5951d76f411475428afc90947ee320161bbf18eb6048", 2], "id": "1"}]

Try running this request with curl and pass true instead of 2 and see if it works. Are you sure it's a bitcoin node and not e.g. bitcoin cash?

@medvedev1088 Thanks for your replying.

I got this:

$ curl --user bitcoin --data-binary '{"jsonrpc": "2.0", "method": "getblock", "params": ["00000000839a8e6886ab5951d76f411475428afc90947ee320161bbf18eb6048", true], "id": "1"}' -H 'content-type: text/plain;' http://127.0.0.1:8332/
Enter host password for user 'bitcoin':

According to the blockhash, it was Bitcoin Cash... I installed 4 full nodes(Ethereum, Bitcoin, Litecoin, Bitcoin Cash), but I might have overwritten btcfullnode by bchfullnode...

I'm gonna check these again.

Thanks for your help!!

Now I can extract data! Thanks a lot!!
