Not a solution, but I'd like to second this issue.
We have a Lua push configured as well, and are currently running dovecot-2.3.14-5 (CentOS 7.9)
After bootstrapping new instances with dovecot 2.3.15 the exact same issue appeared:

The workaround was to downgrade to dovecot-2.3.14-5, and the issues were gone.

Dovecot runs in a Ubuntu 20.04 based container and seems to use the correct liblua5.3:
root@750978e5c0ee:/# dpkg -l|grep -i lua ii dovecot-lua 2:2.3.15-1+ubuntu20.04 amd64 secure POP3/IMAP server - LUA support ii liblua5.3-0:amd64 5.3.3-1.1ubuntu2 amd64 Shared library for the Lua interpreter version 5.3 ii lua-json 1.3.4-2 all JSON decoder/encoder for Lua ii lua-lpeg:amd64 1.0.2-1 amd64 LPeg library for the Lua language ii lua-socket:amd64 3.0~rc1+git+ac3201d-4 amd64 TCP/UDP socket library for the Lua language
Everything was running fine with 2.3.13, have not tried with 2.3.14 yet.
Any ideas?
