end

#outputs ⇒ Object? (readonly)

Note:

Default: - $states.result or $states.errorOutput

Used to specify and transform output from the state.

When specified, the value overrides the state output default. The output field accepts any JSON value (object, array, string, number, boolean, null). Any string value, including those inside objects or arrays, will be evaluated as JSONata if surrounded by % characters. Output also accepts a JSONata expression directly.

Note:

Default: false

#qualifier ⇒ String? (readonly)

Deprecated.

pass a Version or Alias object as lambdaFunction instead

Note:

Default: - Version or alias inherent to the lambdaFunction object.

Version or alias to invoke a published version of the function.

You only need to supply this if you want the version of the Lambda Function to depend on data in the state machine state. If not, you can pass the appropriate Alias or Version object directly as the lambda_function argument.

Returns:

  • (String, nil)
