To Reproduce
Happen once only but I was using:
- Use the chat feature of the genkit.
- Send multiple messages (I sent 12 messages).
- 11 messages succeeded, but 1 message failed with the error above.
simplify code (the real code had pdf sent in each message and real zod schema
import { googleAI } from "@genkit-ai/googleai";
import { genkit, z } from "genkit/beta";
import "dotenv/config";
const prompt = `
You are a helpful assistant.
`; // your prompt here
const ai = genkit({
plugins: [googleAI({})],
model: googleAI.model("gemini-2.5-flash"),
});
(async () => {
const chat = ai.chat({
system: [{ text: prompt }, { text: "You are a helpful assistant." }],
});
for (let i = 0; i < 15; i++) {
console.log(`Sending message ${i + 1}...`);
const quiz = await chat.send({
prompt: [{ text: "how are you" }, { text: prompt }],
output: { schema: z.array(z.string()) },
});
console.log(quiz.output);
}
})();
