You should check your config. From lua code:

   if not obj or not obj.rules or not obj.expression then
   rspamd_logger.errx(cfg, 'cannot add maps combination for module %s: required elements are missing',

So any of object, rule or expression is missing.

See examples: https://rspamd.com/doc/modules/multimap.html#combined-maps
and the hint "Combined maps support merely selectors syntax, not general multimap rules".

As an alternative you can use force_actions to combine symbols:
