invoke_agent#
- AgentsforBedrockRuntime.Client.invoke_agent(**kwargs)#
Note
The CLI doesn’t support streaming operations in Amazon Bedrock, including
InvokeAgent.Sends a prompt for the agent to process and respond to. Note the following fields for the request:
To continue the same conversation with an agent, use the same
sessionIdvalue in the request.To activate trace enablement, turn
enableTracetotrue. Trace enablement helps you follow the agent’s reasoning process that led it to the information it processed, the actions it took, and the final result it yielded. For more information, see Trace enablement.End a conversation by setting
endSessiontotrue.In the
sessionStateobject, you can include attributes for the session or prompt or, if you configured an action group to return control, results from invocation of the action group.
The response is returned in the
bytesfield of thechunkobject.The
attributionobject contains citations for parts of the response.If you set
enableTracetotruein the request, you can trace the agent’s steps and reasoning process that led it to the response.If the action predicted was configured to return control, the response returns parameters for the action, elicited from the user, in the
returnControlfield.Errors are also surfaced in the response.
