I have bedrock this version access and lower anthropic.claude-3-5-sonnet-20240620-v1:0.

So I am getting this error. Seems like model configuration is not passed downstream. I am using proper environment variables as well

Having this sonnet model .

model = BedrockModel(
model_id='anthropic.claude-3-5-sonnet-20240620-v1:0',
temperature=0.0,
top_p=0.0,
streaming=True,
region_name="us-east-1",
)

Step 1: Initialize an agent with agent_graph capability

coordinator_agent = Agent(model=model,tools=[agent_graph])

Errt that I get

model = BedrockModel(
model_id='anthropic.claude-3-5-sonnet-20240620-v1:0',
temperature=0.0,
top_p=0.0,
streaming=True,
region_name="us-east-1",
)

Step 1: Initialize an agent with agent_graph capability

coordinator_agent = Agent(model=model,tools=[agent_graph])

Step 2: Create a structured agent graph using the agent_graph tool

result = coordinator_agent.tool.agent_graph(
action="create",
graph_id="research_team",
topology={
"type": "star",
"nodes": [
{
"id": "coordinator",
"role": "team_lead",
"system_prompt": """You are a research team leader coordinating specialists.
provide a short analysis, no need for follow ups"""
},
{
"id": "data_analyst",
"role": "analyst",
"system_prompt": """You are a data analyst specializing in statistical analysis.
provide a short analysis, no need for follow ups"""
},
{
"id": "domain_expert",
"role": "expert",
"system_prompt": """You are a domain expert with deep subject knowledge.
provide a short analysis, no need for follow ups"""
}
],
"edges": [
{"from": "coordinator", "to": "data_analyst"},
{"from": "coordinator", "to": "domain_expert"},
{"from": "data_analyst", "to": "coordinator"},
{"from": "domain_expert", "to": "coordinator"}
]
}
)

print("Research team created successfully!")
print(f"Result: {result}")

Step 3: Check the status of our newly created network

status_result = coordinator_agent.tool.agent_graph(
action="status",
graph_id="research_team"
)

print("Network Status:")
print(status_result)

Step 4: Send a task to the coordinator

print("Sending task to the coordinator...")

message_result = coordinator_agent.tool.agent_graph(
action="message",
graph_id="research_team",
message={
"target": "coordinator",
"content": """Analyze the impact of remote work on employee productivity.
provide a short analysis, no need for follow ups"""
}
)

print("Task sent to coordinator!")
print(f"Response: {message_result}")
print("============================================================")
print("============================================================")

Step 5: Direct communication with specialists

print("Sending direct message to data analyst...")

analyst_result = coordinator_agent.tool.agent_graph(
action="message",
graph_id="research_team",
message={
"target": "data_analyst",
"content": """What are the key productivity metrics we should
track for remote work analysis? provide a short analysis, no need for follow ups"""
}
)

print(f"Data Analyst Response: {analyst_result}")
print("============================================================")
print("============================================================")

Step 6: List all active networks

print("Checking all active agent networks...")

list_result = coordinator_agent.tool.agent_graph(action="list")
print(f"Active Networks: {list_result}")
print("============================================================")
print("============================================================")

Manage the network

coordinator_agent("Shut down the content research_team when they're done")

Expected Behavior

This framework should use sonnet 3.5 but I think it does not inherit the same model property downstream

Actual Behavior

Error processing message in node coordinator: An error occurred (AccessDeniedException) when calling the ConverseStream operation: You don't have access to the model with the specified model ID.

This error should not occur
