Pricing error connecting to bitcoin regtest

hello, i am attempting to connect the blockstack-core node to a regtest bitcoind instance. Bitcoin is started in the regtest & server mode and blockstack-core is able index transactions. When i run blockstack pricing there is an error - unable to get fee estimate. The debug statements are posted below. Am i missing any other configuration here?

Looks like one of two things:

  • the Blockstack CLI tool couldn’t connect to your permissioned Bitcoin node’s JSON-RPC port
  • you need a newer version of the requests package

Hi @jude

We are able to use curl and fire getbalance and other methods using the same configuration we have in the blockstack-server and blockstack client.

Connect to bitcoind at http://“blockstack”@localhost:18443, timeout=300000.0
[email protected]:~$ curl --data-binary ‘{“jsonrpc”:“1.0”,“id”:“curltext”,“method”:“getbalance”,“params”:[]}’ -H ‘content-type:text/plain;’ http://blockstack:[email protected]:18443
{“result”:5500.00000000,“error”:null,“id”:“curltext”}

However, domain pricing information does not yet appear. I think we are running Python 2.7.

@luckshas fyi

Thanks for posting more details!

Your bitcoind node is clearly up and taking requests. The ResponseNotReady() exception you’re seeing appears to be outside of Blockstack. But, it can be triggered by certain versions of the requests package, which Blockstack uses to talk to bitcoind. Can you tell me which version of requests you’re using?

@jude
it is 2.18.4
$ pip freeze|grep requests
requests==2.18.4

Thanks for confirming!

I’m having a hard time duplicating the problem on my machine. Can you show me the output of running blockstack price with BLOCKSTACK_DEBUG=1 set in the environment?

Alternatively, does this work?

Interesting—you see how it’s trying to connect to http://"blockstack"@localhost:1443? If you look in your ~/.blockstack/client.ini file under the [bitcoind] section, do you have user = "blockstack" or user = blockstack (no quotes)? If you have quotes, can you try removing them? The value for user = is passed as the authentication username as a literal.

yeah i have corrected and that error is not coming up but again I am still unable to get the fee estimate . Could it be because of not enough transactions and blocks on regtest node for estimatefee to generate a fee?
