lnbits: [BUG] Update from 239f166 commit to fe315d0 (origin/main now) failed

Describe the bug

I updated by instruction the version from 239f166a141fa9347ba7ab958c80cbc8804bd8b8 commit to fe315d0a9b97f360c1540509654dce91568bdf45 and cannot run - throw error

To Reproduce Steps to reproduce the behavior:

1. Install 239f166a141fa9347ba7ab958c80cbc8804bd8b8 commit version
2. Set up the config AdminUI version and LndRestWallet type
3. Everything works fine (REST point is OK, macaroon is OK)
4. Update through console as described in “Update LNbits” section to origin/main branch (the current is fe315d0a9b97f360c1540509654dce91568bdf45 commit)
5. Restart LNBits and get errors (with same config and with LNBITS_ADMIN_UI=false too)
6. If I do downgrade - everything works again
