Common Errors

Authentication Errors

LINDY_AUTH_INVALID_KEY

code

Error: Invalid API key provided
Code: LINDY_AUTH_INVALID_KEY

Rate Limit Errors

LINDY_RATE_LIMITED

code

Error: Rate limit exceeded
Code: LINDY_RATE_LIMITED
Retry-After: 60

Causes:

•Too many API requests
•Concurrent agent runs exceeded
•Burst limit reached

Solutions:

typescript

// Implement exponential backoff
async function withBackoff<T>(fn: () => Promise<T>): Promise<T> {
  for (let i = 0; i < 5; i++) {
    try {
      return await fn();
    } catch (e: any) {
      if (e.code === 'LINDY_RATE_LIMITED') {
        const delay = Math.pow(2, i) * 1000;
        await new Promise(r => setTimeout(r, delay));
        continue;
      }
      throw e;
    }
  }
  throw new Error('Max retries exceeded');
}

Agent Errors

LINDY_AGENT_NOT_FOUND

code

Error: Agent not found
Code: LINDY_AGENT_NOT_FOUND

Solutions:

typescript

// Verify agent exists
const agents = await lindy.agents.list();
const exists = agents.some(a => a.id === agentId);

// Check environment (dev vs prod)
console.log('Environment:', process.env.LINDY_ENVIRONMENT);

LINDY_AGENT_TIMEOUT

code

Error: Agent execution timed out
Code: LINDY_AGENT_TIMEOUT

Solutions:

typescript

// Increase timeout
const result = await lindy.agents.run(agentId, {
  input,
  timeout: 120000, // 2 minutes
});

// Use streaming for long tasks
const stream = await lindy.agents.runStream(agentId, { input });

Tool Errors

LINDY_TOOL_FAILED

code

Error: Tool execution failed
Code: LINDY_TOOL_FAILED
Tool: email

Solutions:

typescript

// Check tool configuration
const agent = await lindy.agents.get(agentId);
console.log('Tools:', agent.tools);

// Verify tool credentials
await lindy.tools.test('email');
