describe_execution#

SFN.Client.describe_execution(**kwargs)#

Provides all information about a state machine execution, such as the state machine associated with the execution, the execution input and output, and relevant execution metadata. Use this API action to return the Map Run ARN if the execution was dispatched by a Map Run.

Note

This operation is eventually consistent. The results are best effort and may not reflect very recent updates and changes.

This API action is not supported by EXPRESS state machine executions unless they were dispatched by a Map Run.

Response Structure

  • (dict) –

    • executionArn (string) –

      The Amazon Resource Name (ARN) that identifies the execution.

    • stateMachineArn (string) –

      The Amazon Resource Name (ARN) of the executed stated machine.

    • name (string) –

      The name of the execution.

      A name must not contain:

      • white space

      • brackets < > { } [ ]

      • wildcard characters ? *

      • special characters " # % \ ^ | ~ ` $ & , ; : /

      • control characters ( U+0000-001F, U+007F-009F)

      To enable logging with CloudWatch Logs, the name should only contain 0-9, A-Z, a-z, - and _.

    • status (string) –

      The current status of the execution.

    • startDate (datetime) –

      The date the execution is started.

    • stopDate (datetime) –

      If the execution has already ended, the date the execution stopped.

    • input (string) –

      The string that contains the JSON input data of the execution. Length constraints apply to the payload size, and are expressed as bytes in UTF-8 encoding.

    • inputDetails (dict) –

      Provides details about execution input or output.

      • included (boolean) –

        Indicates whether input or output was included in the response. Always true for API calls.

    • output (string) –

      The JSON output data of the execution. Length constraints apply to the payload size, and are expressed as bytes in UTF-8 encoding.

      Note

      This field is set only if the execution succeeds. If the execution fails, this field is null.

    • outputDetails (dict) –

      Provides details about execution input or output.

      • included (boolean) –

        Indicates whether input or output was included in the response. Always true for API calls.

    • traceHeader (string) –

      The X-Ray trace header that was passed to the execution.

    • mapRunArn (string) –

      The Amazon Resource Name (ARN) that identifies a Map Run, which dispatched this execution.

    • error (string) –

      The error string if the state machine execution failed.

    • cause (string) –

      The cause string if the state machine execution failed.
