# Conflict

> Raised when a request conflicts with the current state of a resource (HTTP 409).

Raised when a request conflicts with the current state of a resource (HTTP 409).

This exception occurs when attempting to perform an operation that conflicts
with the current state of a resource. This typically happens when trying to
create resources that already exist, or when concurrent modifications cause
state conflicts.

Common scenarios include creating models or projects with names that already
exist, attempting to modify resources that are currently being processed,
or violating business rules that prevent certain operations.

## Examples

Handling resource conflicts:

```python theme={null}
try:
    project = client.create_project(name="existing-project")

except Conflict as e:
    print(f"Project already exists: {e.message}")
    # Use existing project or choose different name
    project = client.get_project("existing-project")
```

Handling state conflicts:

```python theme={null}
try:
    model.update_status("active")

except Conflict as e:
    print(f"Cannot change status: {e.message}")
    # Wait for current operation to complete
```

Common Conflict scenarios:

```python theme={null}
- Creating resources with duplicate names
- Modifying resources during processing
- Violating business logic constraints
- Concurrent modification conflicts
```
