I'm getting this line, about 4 times a day:

How it happened ? I do not know but I used to play with Bolt12 when it came out. Now my listoffers shows:

Ah, you can ignore this! The spec for offers is still in draft, and changes. These are old offers we can no longer read, since the format changed.

I see. Can it be purged from db ? I don't see a way to delete it from the lightning-cli command

I need to remove my old PR to do that https://github.com/ElementsProject/lightning/pull/4745 for the moment we have no way to delete an offer!
