Since table in Lua is a reference type and new_messages and conf.prepend
point to the same table, any modification to new_messages will directly affect
the original value of conf.prepend.
I fix the code like this, it works file.
@hw872715125 can you try this ?
` local function decorate(conf, body_tab)
- local new_messages = conf.prepend or EMPTY
+ local new_messages = {}
+ if conf.prepend then
+ for i = 1, #conf.prepend do
+ new_messages[i] = conf.prepend[i]
+ end
+ end
+
for _, message in pairs(body_tab.messages) do
core.table.insert_tail(new_messages, message)
end
`
