| protected\_mode | If enabled, Lua script will be executed in protected mode. It prevents Fluent Bit from crashing when invalid Lua script is executed or the triggered Lua function throws exceptions. Default is true. |
| time\_as\_table | By default when the Lua script is invoked, the record timestamp is passed as a *floating number* which might lead to precision loss when it is converted back. If you desire timestamp precision, enabling this option will pass the timestamp as a Lua table with keys `sec` for seconds since epoch and `nsec` for nanoseconds. |
| code | Inline LUA code instead of loading from a path via `script`. |
| enable_flb_null| If enabled, null will be converted to flb_null in Lua. It is useful to prevent removing key/value since nil is a special value to remove key value from map in Lua. Default is false. |
