Electrs 0.12.0:6 crash-loops with REST 404 on Bitcoin Core 31.2:0

Bitcoin Core 31.2:0 is fully synced and shows as Satisfied (>=31.1:17) in Electrs’s dependencies. Electrs 0.12.0:6 exits with code 1 on every start. I tried stopping both, starting Bitcoin Core first, then Electrs; same result.

Log:

Error: electrs failed
Caused by:
  0: sync failed
  1: client failed: request failed: http status: 404

Possibly Electrs reaching the btc-rpc-proxy instead of the direct REST listener after the 31.2:0 update?
