Pigeonhole managesieve-login panic

Hi folks,

I'm getting a

Dec 19 16:18:07 managesieve-login: Panic: file client.c: line 350 (managesieve_client_input_next_cmd): assertion failed: (args != NULL)
Dec 19 16:18:07 auth: Debug: conn unix:login (pid=7390,uid=91) [2]: Disconnected: Connection closed (fd=20)
Dec 19 16:18:07 managesieve-login: Fatal: master: service(managesieve-login): child 7390 killed with signal 6 (core dumps disabled - https://dovecot.org/bugreport.html#coredumps)

When trying to connect to MANAGESIEVE using sieve-connect. The command I'm using is

sieve-connect -s revsuine.xyz -u pid1 --passwordfd=5 5<<<"$(command to get pass here)"

This command was working previously (within the past year), though I don't remember which versions of Dovecot/Pigeonhole I tried it on. sieve-connect has not been updated recently, so there aren't any changes in sieve-connect that would've caused this.

I'm attaching the files generated by dovecot-sysreport which includes my dovecot -n.

Server OS is Alpine Linux 3.23.2.
