how to set untrusted_lua_sandbox_requires env in docker-compose.yaml

[wangqinghuan]

I need to decompress response_body using code like

local utils = kong.tools.utils
local raw_response_body = kong.response.get_raw_body()
if raw_response_body and kong.response.get_header("Content-Encoding") == "gzip" then
    local decompressed_response, err = utils.inflate_gzip(raw_response_body)
    if not decompressed_response then
        kong.log.err("Failed to decompress response body: ", err)
    else
       kong.log.set_serialize_value("response.body", decompressed_response) 
    end
else
   kong.log.set_serialize_value("response.body", raw_response_body)
end

Then got a response
2025/07/30 14:45:50 [error] 1410#0: *20687 failed to run body_filter_by_lua*: /usr/local/share/lua/5.1/kong/tools/kong-lua-sandbox.lua:164: [string "local utils = kong.tools.utils..."]:1: attempt to index field 'tools' (a nil value

By this document, we need to add kong.tools.utils to untrusted-lua-sandbox-requires.

Then I add KONG_UNTRUSTED_LUA_SANDBOX_REQUIRES environment in docker-compose.yaml.

kong:
    image: "${KONG_DOCKER_TAG:-kong:latest}"
    user: "${KONG_USER:-kong}"
    environment:
      <<: *kong-env
      KONG_ADMIN_ACCESS_LOG: /dev/stdout
      KONG_ADMIN_ERROR_LOG: /dev/stderr
      KONG_PROXY_LISTEN: "${KONG_PROXY_LISTEN:-0.0.0.0:8000}"
      KONG_ADMIN_LISTEN: "${KONG_ADMIN_LISTEN:-0.0.0.0:8001}"
      KONG_ADMIN_GUI_LISTEN: "${KONG_ADMIN_GUI_LISTEN:-0.0.0.0:8002}"
      KONG_PROXY_ACCESS_LOG: /dev/stdout
      KONG_PROXY_ERROR_LOG: /dev/stderr
      KONG_PREFIX: ${KONG_PREFIX:-/var/run/kong}
      KONG_DECLARATIVE_CONFIG: "/opt/kong/kong.yaml"
      KONG_UNTRUSTED_LUA_SANDBOX_REQUIRES: "kong.tools.utils"

Unfortunately, Kong still says
` [string "local utils = kong.tools.utils..."]:1: attempt to index field 'tools' (a nil value``

By passing environment in shell command also not work for me,

KONG_UNTRUSTED_LUA_SANDBOX_REQUIRES="kong.tools.utils" docker-compose --profile database up

How to make untrusted-lua-sandbox-requires effect?
