Bedrock agent invokation does not return "returnControl" element

Question

All,
in my Python call i am trying to invoke my agent. Agent is instructed to call a specific function for certain condition.
Call Is:
agent = BedrockAgent(agentAliasId='...',agentId='...')
response = agent.invokeWithFunction(
        enableTrace=True,
        endSession=False,
        prompt='provede...',
        )
in a console agent asks for specific function information. in Python, trace is also indicates that function should be invilved.
The problem is that is i do not see returnControl element in response.
Agent and Agent alias are verified and action is "return control" in a console definition.
Any help would be appreciated
Thank you

That was a bug in boto3. Latest version - 1.34.111 - works

Answer

Hello.

If you execute invoke_agent() as is, the response will include "returnControl".  
Have you tried running invoke_agent()?

Answer

yes, and it does not return "returnControl". 
---------------------------------

class BedrockAgent:
    def __init__(self, agentId = "..", agentAliasId= "", name = "bedrock-agent-runtime", verify = False):
        self.agentId = agentId 
        self.agentAliasId = agentAliasId
        self.client = boto3.client(name, verify=verify)

def invokeWithFunction(self, prompt, enableTrace=False, endSession=True, sessionId=str(uuid.uuid4())):
        response = self.client.invoke_agent(
            agentAliasId= self.agentAliasId,
            agentId=self.agentId,
            enableTrace=enableTrace,
            endSession=endSession,
            inputText=prompt,
            sessionId=sessionId)
        return response

--------------------------------------------------------
agent = BedrockAgent(agentAliasId='...',agentId='...')
response = agent.invokeWithFunction(
        enableTrace=True,
        endSession=False,
        prompt='please find ...',
        )
completion = response.get("completion")
if completion:
    for event in completion:
        print("----------- Event -----------------")
        print(event)

Thank you,
