Parameter

Description

Example

Basic Settings

State Name

The name of the state node. The name describes the feature of the state.

InvokeFunction

Invocation Parameters

The name, version or alias, and invocation method of the function that you want to invoke, and payloads that trigger the function.

You can also click Switch to YAML Editing next to Invocation Parameters to specify the name, version or alias, and invocation method of the function in a YAML script.

A sample YAML script:

invocationType: Sync
resourceArn: acs:fc:cn-beijing:1034354682****:functions/GPU-demo/LATEST
body:
  key: value

Function

The name of the function that you want to invoke.

myfunction

Version or Alias

The version or alias of the function that you want to invoke.

LATEST

Function Invocation Method

The method that you want to use to invoke the function. Valid values: Sync Invocation and Async Invocation. For more information about function invocation methods, see Function invocation.

Sync Invocation

Request Load

The payloads that trigger the function. You can enter payloads in the YAML or JSON format.

{
  "key1": "value1",
  "key2.$": "$.myStateInput.key",
  "key3": 100
}

Next State

The next state to which you want the flow to transition. The setting takes effect in real time.

Parallel

Input Settings

The filtering method of inputs. Valid values:

• Use JSONPath to select some parameters: Enter a filter expression in the code editor. Use JSONPath to filter parameter objects as the node input.

• Original inputs as node inputs: Use the original input of the node as the node input.

• Use parameter filters to construct parameters: Use parameter filters to construct new parameters as the node input. You can construct parameters in the YAML or JSON format. Example:

  FieldA: 123
  FieldB: string
  FieldC.$: $Input

Output Settings

The filtering method of outputs. Valid values:

• Use JSONPath to select some parameters: Enter a filter expression in the code editor. Use JSONPath to filter parameter objects of valid output as the node output.

• Pass raw inputs to outputs: Pass the original input of the node downstream as output.

• Use parameter filters to construct parameters: Use parameter filters to construct new parameters as the node output. You can construct parameters in the YAML or JSON format. Example:

  FieldA: 123
  FieldB: string
  FieldC.$: $Input

Troubleshooting

Retry upon Error: The retry policy when an error is caught. Click Add Retry to add retry policies.

Error Type

The error types that can be hit. You can select one or more error types.

FC.BadResponse

Maximum Retries

The allowed maximum number of retries.

5

Retry Interval Seconds

The retry interval. Maximum value: 86400. Unit: seconds.

3

Backoff Multiplication Factor

The multiplier by which the retry interval increases.

1

Maximum Backoff Seconds

The maximum period of time within which retries must be performed in exponential fallback mode. Unit: seconds.

5

Capture errors and exceptions: The capture rule that restores the flow to an expected state when an error or exception is caught. Click Add Capture Rule to add capture rules.

Error Type

The error types that can be hit. You can select one or more error types.

FC.EntitvToolLarge

Fallback Status

The state to which the flow returns when a specified error is caught.

Hello World

Response

The result that is returned when a specified error is caught. The result contains the error and the error is added to the input of the fallback node. You can configure a response in the YAML or JSON format.

{
"key":string"hello world"
}
