Return Value

The return value from the call is the value returned from the given reactor.

Recursions and Loops

By having a reactor call itself it's possible to introduce recursion, and more specifically infinite recursion. To prevent this and ensure stable operations, there's a max call depth that will trigger an error. The limit for cloud instances are 10 calls, while enterprise instances may configure this.

Error Handling

Error may be returned if the specified reactorId or method doesn't exist, or the given argument is invalid.

Examples

from invokeReactor(
  'myReactor',
  'myMethod'
) match
  Error |> 'An error occurred'
  (result: value) |> result
