@whitslack I'm unable to reproduce this, any theory onto what could be producing it?

[whitslack]

The test sends coins from node 0 to node 1 and then mines a block on node 0 but does not wait for node 1 to see the new block before the test attempts to fund a raw transaction on node 1.

Edit: It appears as though the generate method handles waiting for the new block to be processed by the other nodes, so that's probably not the problem. Looking at the combined log (linked above), the last block generated by node 0 is indeed logged by UpdateTip on node 1 (and an AddToWallet … new is also logged) before the "Fund the raw transaction" step. However, this does look suspect: node1 2025-02-11T15:22:23.466642Z [httpworker.0] [wallet/coinselection.cpp:312] [KnapsackSolver] Not enough funds to create target 45000000000 for asset 0c2260c615ccc4a503f9a5ddb10d1ed0da56196d6602a95adf4379899cceb236. Are coins considered spendable by fundrawtransaction when they have only 1 confirmation?

It would be helpful if the test logged more information about the state of the wallet in the event of a failure. In particular, it would be good to see the output of listunspent so we can tell whether all 45 UTxOs are in fact present and spendable.
