Unable to start loop in integrated mode: sql: Scan error on column index 20, name "publication_deadline"

[MButcho]

When I loop out, I get green confirmation windows, but nothing shows as initiated.

Expected behavior I expect:

Actual behavior No loop out is showing. I opened loop_sqlite.db and checked data:

To reproduce Every time I loop out, I receive weird date in DB. LND and all is running well.

System information I am using Lightning Terminal standalone with this in litd.conf: lnd-mode=integrated Running v0.10.4-alpha downloaded lightning-terminal-linux-amd64-v0.10.4-alpha.tar.gz from https://github.com/lightninglabs/lightning-terminal/releases/tag/v0.10.4-alpha Running local node with Ubuntu 22.04 and SSD

When I restart a service with wrong date, this is the error in litd.log: 2023-08-05 12:07:26.324 [INF] LOOPD: Opening sqlite3 database at: /home/litd/.loop/mainnet/loop_sqlite.db 2023-08-05 12:07:26.445 [WRN] GRPC: [core] grpc: addrConn.createTransport failed to connect to {swap.lightning.today:11010 swap.lightning.today:11010 0 }.

When I switched to lnd-mode=remote, I get Initiated transaction in loop out tab, the transaction goes through, but the sqlite db still showing invalid dates for the new transaction:

We've had several users encounter the same (or very similar) error on Lit v0.10.2-alpha today:

For at least this user, LiT will not start due to this error.

[ellemouton]

LiT will not start due to this error.

Just noting here that once #541 is in, then an error in one of the subservers wont prevent the rest of LiT from starting up 👍

[sputn1ck]

Thanks for reporting this.

Are the swaps created manually via terminal-web/lightning-terminal or via autoloop?

[MButcho]

Manually via terminal-web, I don't use autoloops :)

[sputn1ck]

Okay, I found the origin of the bug. We were using milliseconds instead of seconds as unix time, which is why those dates are super far in the future. Prior to sqlite we would be storing those milliseconds directly. With sqlite we switched over to timestamp strings, which is why this surfaced now.

We're currently discussing which parts to change. Fix will be out soon™
