Database request error : "Attempt to yield across C-call boundary"

[iThorgrim]

Hello,

I am encountering an issue while using lapis.db.query in an OpenResty environment with Lua 5.1. When executing a simple SQL query via lapis.db.query, the following error occurs:

2024/08/24 13:18:11 [error] 4349#4349: *1 lua entry thread aborted: runtime error: attempt to yield across C-call boundary
stack traceback:
coroutine 0:
        [C]: in function 'require'
        /usr/local/share/lua/5.1/lapis/init.lua:15: in function 'serve'
        content_by_lua(nginx.conf.compiled:22):2: in main chunk, client: 127.0.0.1, server: , request: "GET / HTTP/1.1", host: "127.0.0.1:8080"

Here is a minimal example of my code:

local db = require("lapis.db")

function model.loadModules()
    local result = db.query("SELECT * FROM modules WHERE active = 1")
    error("ok")
    -- Further processing
end

The error occurs immediately after executing the SQL query, even before reaching the error("ok") statement.

I am confident that the issue is related to the execution of the SQL query, as the error disappears when I comment out the db.query call.

Environment:

• OpenResty
• Lua 5.1 (Tested with Lua5.2, Lua5.3, Lua5.4, LuaJit)
• Lapis version 1.16.0
• Database used: Mariadb (with libmariadb-compat installed)
• Linux Debian 12

Note:
All dependencies are up to date. I have not modified the default configuration of Lapis (only for addin my DB, like this : mysql = {host = "127.0.0.1", user = "bob", password = "bob", database = "prod_website"}
