return await prompts.getPrompt({
promptName: "primary-prompt",
timeout: 5000,
});
} catch (error) {
console.error("Prompt fetch failed:", error);
return "You are a helpful assistant."; // Fallback
}
};
```
### Common Errors
#### Prompt Not Found
```typescript
// Error: Prompt 'weather-prompt' not found
// Solution: Verify prompt name exists in VoltOps console
instructions: async ({ prompts }) => {
try {
return await prompts.getPrompt({ promptName: "weather-prompt" });
} catch (error) {
console.error("Prompt fetch failed:", error);
return "Fallback instructions";
}
};
```
#### Missing Variables
```typescript
// Error: Variable 'userName' not found in template
// Solution: Provide all required variables with defaults
return await prompts.getPrompt({
promptName: "greeting-prompt",
variables: {
userName: context.get("userName") || "Guest",
currentTime: new Date().toISOString(),
},
});
```
#### Authentication Failed
```typescript
// Error: Authentication failed
// Solution: Verify environment variables
console.log("Public Key:", process.env.VOLTAGENT_PUBLIC_KEY?.substring(0, 8) + "...");
console.log("Secret Key:", process.env.VOLTAGENT_SECRET_KEY ? "Set" : "Missing");
```
#### Stale Cache
```typescript
// Problem: Old prompt version still in use after update
// Solution 1: Clear cache
voltOpsClient.prompts.clearCache();
// Solution 2: Disable cache temporarily
return await prompts.getPrompt({
promptName: "urgent-prompt",
promptCache: { enabled: false },
});
// Solution 3: Wait for TTL expiration
```
## Debugging
Test prompt fetching independently:
```typescript
const voltOpsClient = new VoltOpsClient({
publicKey: process.env.VOLTAGENT_PUBLIC_KEY,
secretKey: process.env.VOLTAGENT_SECRET_KEY,
});
try {
const prompt = await voltOpsClient.prompts.getPrompt({
promptName: "test-prompt",
});
console.log("Success:", prompt);
} catch (error) {
console.error("Failed:", error);
}
```
## Complete Example
```typescript
import { openai } from "@ai-sdk/openai";
import { Agent, VoltAgent, VoltOpsClient } from "@voltagent/core";
const voltOpsClient = new VoltOpsClient({
publicKey: process.env.VOLTAGENT_PUBLIC_KEY,
secretKey: process.env.VOLTAGENT_SECRET_KEY,
