Chaining supervisor agent with agents which own vector tools does not work
Agent
I have created a supervisor agent, which has a tool calling agent B. Agent B has an access to the vector tool and if called directly - it works. However when it is invoked from another tool, then I get the following error:
Agent B looks like this:
and it works if called separately.
Vector tool looks like this:
{
"message": "Invalid schema for function 'vectorTool': In context=('additionalProperties',), schema must have a 'type' key.",
"details": {
"message": "Invalid schema for function 'vectorTool': In context=('additionalProperties',), schema must have a 'type' key.",
"domain": "TOOL",
"category": "USER",
"details": {
"errorMessage": "[Agent:Agent B] - Failed tool execution",
"argsJson": "{\"brief\":\"A.\",\"pov\":\"customer\",\"endingType\":\"quiz\"}",
"model": "gpt-4o-mini"
}
},
"code": "TOOL_EXECUTION_FAILED"
}Agent B looks like this:
export const agentB = new Agent({
name: "Agent B",
instructions: async ({
runtimeContext,
}: {
runtimeContext: RuntimeContext<SomeRuntimeContext>;
}) => {
return getPrompt(
runtimeContext.get("brief"),
runtimeContext.get("pov"),
runtimeContext.get("endingType")
)
},
model: openai("gpt-4o-mini"),
tools: { vectorTool }
});and it works if called separately.
Vector tool looks like this:
export const vectorTool = createVectorQueryTool({
id: "get-sample-results-vector",
description: "Query the style guideline RAG.",
vectorStoreName: 'ragStore',
indexName: 'myrags',
model: openai.embedding("text-embedding-3-small"),
databaseConfig: {
pgvector: {
minScore: 0.2,
ef: 400,
probes: 75,
},
}
});
