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 sessionId value in the request.

• To activate trace enablement, turn enableTrace to true. 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 endSession to true.

• In the sessionState object, 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 contains both chunk and trace attributes.

The final response is returned in the bytes field of the chunk object. The InvokeAgent returns one chunk for the entire interaction.

• The attribution object contains citations for parts of the response.

• If you set enableTrace to true in 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 returnControl field.

• Errors are also surfaced in the response.
