# Error Handling

> Managing errors with the Pipecat Cloud Python SDK

The Pipecat Cloud SDK defines several exception classes to help you handle different error conditions.

## Base Exception Class

### Error

Base class for all Pipecat Cloud exceptions.

```python  theme={null}
from pipecatcloud.exception import Error

try:
    # SDK operation
except Error as e:
    print(f"A Pipecat Cloud error occurred: {e}")
```

## Session Errors

### AgentStartError

Raised when an agent fails to start.

```python  theme={null}
from pipecatcloud.exception import AgentStartError

try:
    response = await session.start()
except AgentStartError as e:
    print(f"Failed to start agent: {e}")
    if e.error_code == "429":
        print("Agent pool at capacity. Try again later.")
    elif e.error_code == "404":
        print("Agent not found.")
```

#### Properties

<ParamField path="message" type="string">

    print(f"Agent is not ready: {e}")
    print("Check agent status with: pipecat cloud agent status my-agent")
