IncompatibleClient

This exception occurs during connection initialization when the client library version is not compatible with the connected Fiddler platform version. This ensures that users are aware of version mismatches that could cause unexpected behavior or missing functionality. The exception includes both the client version and server version in the error message to help users understand what versions are involved in the incompatibility.

Examples

Handling version incompatibility:

try:
    fdl.init(url="https://old-fiddler.com", token="token")

except IncompatibleClient as e:
    print(f"Version mismatch: {e.message}")
    # Upgrade client or contact administrator

Typical error message format:

"Python Client version (3.8.0) is not compatible with your
Fiddler Platform version (3.5.0)."
