Conflict - Fiddler Documentation

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:

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:

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:

- Creating resources with duplicate names
- Modifying resources during processing
- Violating business logic constraints
- Concurrent modification conflicts
