BedrockInvokeModel

A Step Functions Task to invoke a model in Bedrock.

Import

import { BedrockInvokeModel } from 'aws-cdk-lib/aws-stepfunctions-tasks';

Or use the module namespace:

import * as stepfunctions_tasks from 'aws-cdk-lib/aws-stepfunctions-tasks';
// stepfunctions_tasks.BedrockInvokeModel

Properties

Configuration passed to the constructor as BedrockInvokeModelProps.

modelRequired

IModel

The Bedrock model that the task will invoke.

acceptOptional

string

The desired MIME type of the inference body in the response.

Default: 'application/json'

bodyOptional

TaskInput

The input data for the Bedrock model invocation. The inference parameters contained in the body depend on the Bedrock model being used. The body must be in the format specified in the `contentType` field. For example, if the content type is `application/json`, the body must be JSON formatted. The body must be up to 256 KB in size. For input data that exceeds 256 KB, use `input` instead to retrieve the input data from S3. You must specify either the `body` or the `input` field, but not both.

Default: - Input data is retrieved from the location specified in the `input` field

contentTypeOptionalDeprecated

string

The MIME type of the input data in the request.

Default: 'application/json'

Deprecated: This property does not require configuration because the only acceptable value is 'application/json'.

guardrailOptional

Guardrail

The guardrail is applied to the invocation.

Default: - No guardrail is applied to the invocation.

inputOptional

BedrockInvokeModelInputProps

The source location to retrieve the input data from.

Default: - Input data is retrieved from the `body` field

outputOptional

BedrockInvokeModelOutputProps

The destination location where the API response is written. If you specify this field, the API response body is replaced with a reference to the output location.

Default: - The API response body is returned in the result.

traceEnabledOptional

boolean

Specifies whether to enable or disable the Bedrock trace.

Default: - Trace is not enabled for the invocation.

2 properties inherited from TaskStateBaseProps

resultPathOptionalinherited from TaskStateBaseProps

string

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.

Default: $

resultSelectorOptionalinherited from TaskStateBaseProps

{ [key: string]: any }

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.

Default: - None

3 properties inherited from StateBaseProps

commentOptionalinherited from StateBaseProps

string

A comment describing this state.

Default: No comment

queryLanguageOptionalinherited from StateBaseProps

QueryLanguage

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.

Default: - JSONPath

stateNameOptionalinherited from StateBaseProps

string

Optional name for this state.

Default: - The construct ID will be used as state name

6 properties inherited from TaskStateBaseOptions

credentialsOptionalinherited from TaskStateBaseOptions

Credentials

Credentials for an IAM Role that the State Machine assumes for executing the task. This enables cross-account resource invocations.

Default: - None (Task is executed using the State Machine's execution role)

heartbeatOptionalDeprecatedinherited from TaskStateBaseOptions

Duration

Timeout for the heartbeat.

Default: - None

Deprecated: use `heartbeatTimeout`

heartbeatTimeoutOptionalinherited from TaskStateBaseOptions

Timeout

Timeout for the heartbeat. [disable-awslint:duration-prop-type] is needed because all props interface in aws-stepfunctions-tasks extend this interface

Default: - None

integrationPatternOptionalinherited from TaskStateBaseOptions

IntegrationPattern

AWS Step Functions integrates with services directly in the Amazon States Language. You can control these AWS services using service integration patterns. Depending on the AWS Service, the Service Integration Pattern availability will vary.

Default: - `IntegrationPattern.REQUEST_RESPONSE` for most tasks. `IntegrationPattern.RUN_JOB` for the following exceptions: `BatchSubmitJob`, `EmrAddStep`, `EmrCreateCluster`, `EmrTerminationCluster`, and `EmrContainersStartJobRun`.

taskTimeoutOptionalinherited from TaskStateBaseOptions

Timeout

Timeout for the task. [disable-awslint:duration-prop-type] is needed because all props interface in aws-stepfunctions-tasks extend this interface

Default: - None

timeoutOptionalDeprecatedinherited from TaskStateBaseOptions

Duration

Timeout for the task.

Default: - None

Deprecated: use `taskTimeout`

1 property inherited from AssignableStateOptions

assignOptionalinherited from AssignableStateOptions

{ [key: string]: any }

Workflow variables to store in this step. Using workflow variables, you can store data in a step and retrieve that data in future steps.

Default: - Not assign variables

2 properties inherited from JsonPathCommonOptions

inputPathOptionalinherited from JsonPathCommonOptions

string

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 {}.

Default: $

outputPathOptionalinherited from JsonPathCommonOptions

string

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 {}.

Default: $

1 property inherited from JsonataCommonOptions

outputsOptionalinherited from JsonataCommonOptions

any

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.
