Modify the constraint to reference the auto-derived clock by the pin name attached to the clock using [get_clocks -of_objects [get_pins <PIN_NAME>]].

Alternatively, use the create_generated_clock constraint to force the name of the auto-derived clock. An auto-derived clock can be renamed even after being referenced by other timing constraints. For more information about using a generated clock constraint to force a clock name, refer to the Vivado Design Suite User Guide: Using Constraints (UG903).
