I am trying to implement a tool with genkit that queries a firestore database to support responding to certain types of prompts. It errored out when I added it and I have been able to narrow down the problem to a combination of using the context from a retriever with Gemini calling one of the tools I made available to it.
The error is:
{"severity":"ERROR","message":"Unhandled error Error: Vertex response generation failed: ClientError: [VertexAI.ClientError]: Within a single message, FunctionResponse cannot be mixed with other type of part in the request for sending chat message.\n at /xxxxxx/node_modules/@genkit-ai/vertexai/lib/gemini.js:514:17\n at Generator.throw ()\n at rejected (/xxxxxxx/node_modules/@genkit-ai/vertexai/lib/gemini.js:50:29)\n
at process.processTicksAndRejections (node:internal/process/task_queues:95:5)"}
The error goes away when I comment out passing in the context to the prompt generate method. Here is the sample code:
const myTool = defineTool(
{
name: "myTool",
description:
"When a question about the calendar bookings or reservations is asked, this tool will load the calendar booking data.",
inputSchema: z.object({
beginDate: z
.string()
.optional()
.describe("The beginning date to load the calendar data for."),
endDate: z
.string()
.optional()
.describe("The end date to load the calendar data for."),
member: z
.string()
.optional()
.describe("The member ID or name to filter the calendar bookings by."),
}),
outputSchema: z.string(),
},
async (input) => "haha Just kidding no joke about for you! got you"
);
const myRetrieverRef = defineFirestoreRetriever({
name: "retriever-id",
firestore: getFirestore(),
collection: "calendar/vectorIndex",
contentField: "content",
vectorField: "embedding",
embedder: textEmbeddingGecko,
distanceMeasure: "COSINE", // 'EUCLIDEAN', 'DOT_PRODUCT', or 'COSINE' (default)
});
const docs = await retrieve({
retriever: myRetrieverRef,
query: userMessage,
options: {
limit: 5,
k: 3,
},
});
const myPrompt = await prompt("myBot");
const result = await myPrompt.generate({
input: {
message: userMessage,
today: format(new Date(), "yyyy-MM-dd"), // "2022-01-01
user: {
id: request.auth?.uid || "anonymous",
name: request.auth?.token.name || "anonymous",
},
},
context: docs, // when I comment out this line the error goes away regardless of what tool I include, I've tried a few different versions of it
tools: [myTool],
});
Here is the console information from genkit running the prompt when it errors out because the context was provided. I should note that I've tried with gemini-1.0-pro as well before switching to try the new 1.5 versions.

It just seems that right now that it is not possible to mix user and function content: gemini.js link
function assignRoleToPartsAndValidateSendMessageRequest(
...
if (hasUserContent && hasFunctionContent) {
throw new GoogleGenerativeAIError(
"Within a single message, FunctionResponse cannot be mixed with other type of part in the request for sending chat message.",
);
}
