Unhandled error: "builtins.IndexError: tuple index out of range"

[Ulawun]

Hello :-)

The ghcr.io/joinmarket-webui/jam-standalone container is running,
JoinMarket is running,
but doesn't mix continuously.
I'm a maker and charge no (absolute) fees.
JoinMarket mixed twice, which this is one month ago.
For one month now there's no further mixing :-(

I'm running bitcoin core and
the ghcr.io/joinmarket-webui/jam-standalone container on one computer.
Computer: Linux Mint 21.3 Virginia 64-bit
Bitcoin core: v27.1.0
Docker: 24.0.7, build: ubuntu...
ghcr.io/joinmarket-webui/jam-standalone: v0.3.0

Initially I transferred BTC to wallet A.
Then JoinMarket mixed twice to wallet B.
Then it stopped mixing till now (for one month).

I restarted the backend several times,
but that didn't change the symptoms.

Every view hours (a view times a day) I get the same
unhandled error: "builtins.IndexError: tuple index out of range".
A snippet of the logs looks like this:

Is there any solution ?

Same issue here, running just JM 0.9.11 as a maker (no jam, no docker, Ubuntu 24.04.1 ):

[Fonta1n3]

I get the same on macOS when initiating a coinjoin via the API, running v0.9.11. Will try downgrading.

[Fonta1n3]

Downgrading resulted in other install issues.. Sticking with current version and am able to replicate it repeatedly on different machines.
