GetBlockTemplate no longer works about bitcoinlib HOT 4 CLOSED

Hi there,
Since Bitcoin 0.13.1 (segwit), the getblocktemplate() method no longer returns anything.

I think this is due to the fact that you now need to specify a rule when calling getblocktemplate. For example, if you call:

bitcoin-cli getblocktemplate
You get this error:

error code: -8
error message:
Support for 'segwit' rule requires explicit client support

To get it working, you have to pass a rule like this as an extra argument, like so:

bitcoin-cli getblocktemplate '{"rules":["segwit"]}'

I'm trying with this:
CoinService.GetBlockTemplate("'{\"rules\":[\"segwit\"]}'")
but the result is:
"{\"result\":null,\"error\":{\"code\":-1,\"message\":\"JSON value is not an object as expected\"},\"id\":1}\n"
Is there any way to pass this argument to the CoinService.GetBlockTemplate() method to get it working again?

Against my 0.19.1 Bitcoin Core node, this call works:

var blockTemplate = CoinService.GetBlockTemplate( new { rules=new List<string> { "segwit" } });

So by supplying the parameters as an anonymous type you should be able to get the call to work. If you think the interface should work differentely, let me know.

@idt-byte, thank you for reporting this 👍 I apologize for the delay, I hope @Sword-Smith can look into this (as per #116). Let’s give @Sword-Smith 3 days to respond.

Closing this as it works and the interface in my opinion is OK
