Workflow variables to store in this step.
Using workflow variables, you can store data in a step and retrieve that data in future steps.
comment?
Type:
string
(optional, default: No comment)
A comment describing this state.
inputPath?
Type:
string
(optional, default: $)
JSONPath expression to select part of the state to be the input to this state.
May also be the special value JsonPath.DISCARD, which will cause the effective input to be the empty object {}.
outputPath?
Type:
string
(optional, default: $)
JSONPath expression to select part of the state to be the output to this state.
May also be the special value JsonPath.DISCARD, which will cause the effective output to be the empty object {}.
outputs?
Type:
any
(optional, 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.
queryLanguage?
Type:
Query
(optional, default: JSONPath)
The name of the query language used by the state.
If the state does not contain a queryLanguage
field,
then it will use the query language specified in the top-level queryLanguage
field.

string
(optional, default: The construct ID will be used as state name)
Optional name for this state.
