Error: `cannot acquire wallet lock, null`

[da-kami]

Context of when this happened:

• Likely unrelated:
  • Lucas sent me Bitcoin
  • I opened a channel (worked)
  • The channel open tx was confirmed
  • Created an invoice
  • Lucas tried to pay it but it failed
  • The "receive" was pending forever
• I tried to open a CFD, I ran into the problem below after clicking Confirm:

I fixed the spot where it errored - I assume we are holding the lock for too long here: https://github.com/itchysats/10101/blob/main/rust/src/wallet.rs#L519

I don't think this can be the problem because this is open_channel and we are able to e.g. open a cfd afterwards.

When trying again I actually noticed that there was another error prior to the wallet lock error (on my retry) - I am not sure it is related but it could be:

I think the problem is related to my balance not being enough and opening the CFD failing - why the wallet would remain locked after that I cannot understand 😅

For the release: Only invest time into this once all other tickets are done, this is likely a timesink :)
