[Rspamd-Users] set_metric_action?

[Aki Kyo]

hi, I was using task:set_metric_action in a custom post-filter lua script:

task:set_metric_action('', 'add header')

the reason to use it is complex, force_action module could not
suffice. In recent rspamd release, is set_metric_action deprecated? It
has gone missing from Lua Task documentation page:

https://www.rspamd.com/doc/lua/rspamd_task.html

also it's broken:

task; lua_metric_symbol_callback_error: call to (my_postfilter_script)
failed (2): /etc/rspamd/rspamd.local.lua:143: attempt to call method
'set_metric_action' (a nil value);

What's the new way to do this?
