inputPath?
Type:
string
(optional, default: $)
JSONPath expression to select part of the state to be the input to this state.

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).

You can use these properties to pass key value pairs to your main function.
queryLanguage?

If the state does not contain a queryLanguage
field,
then it will use the query language specified in the top-level queryLanguage
field.
resultPath?
Type:
string
(optional, default: $)
JSONPath expression to indicate where to inject the state's output.
May also be the special value JsonPath.DISCARD, which will cause the state's input to become its output.
resultSelector?
Type:
{ [string]: any }
(optional, default: None)
The JSON that will replace the state's raw result and become the effective result before ResultPath is applied.
You can use ResultSelector to create a payload with values that are static or selected from the state's raw result.
stateName?
Type:
string
(optional, default: The construct ID will be used as state name)
Optional name for this state.
taskTimeout?
Type:
Timeout
(optional, default: None)
Timeout for the task.

timeout?
⚠️ Deprecated: use taskTimeout
Type:
Duration
(optional, default: None)
Timeout for the task.
