analyzepsbt causes elementsd to crash with assertion when given a funded psbt

Open asoltys opened this issue 5 years ago • 1 comments

I created a funded psbt with walletcreatefundedpsbt like so:

elements-cli walletcreatefundedpsbt [] "[{\"AzpxinPHtswVettidEhUXDeWjo3msP1A9Je5LFhQaQn5Ppf8owJCpDwjiQ6EF9YqXBAMU7BA4MKaJbba\": 0.005}]"

Got back this base64:

Passing the base 64 to analyzepsbt causes my daemon to crash:

error: Could not connect to the server 127.0.0.1:18882 (error code 1 - "EOF reached")

Make sure the daemon server is running and that you are connecting to the correct RPC port.

With this in the debug.log:

elementsd: ./primitives/confidential.h:140: CAmount CConfidentialValue::GetAmount() const: Assertion `IsExplicit()' failed.

I just had the same problem, except that analyzepsbt worked fine before I ran utxoupdatepsbt, after the utxo information were added it seems to make the node crash reliably.

There's nothing on my debug.log though.

Hope this helps.
