Dispatching multiple actions in parallel throws an error

[Tam]

According to the docs, it should be possible to dispatch multiple actions in parallel by passing an array of actions to the store:

// dispatch multiple object in parallel
socrates([
  { type: 'change:name', payload: { name: 'an' }},
  { type: 'change:age', payload: { age: 26 }}
])

But when I attempt this, I get the following redux error:
Error: Actions must be plain objects. Use custom middleware for async actions.

My code:

const slots = { /* a plain object */ }
    , exceptions = { /* a plain object */ };

store([
  { type: "set:slots", payload: slots },
  { type: "set:exceptions", payload: exceptions },
]);

Running each action individually works without issue:

store("set:slots", slots);
store("set:exceptions", exceptions);
