API Status: -6 : Range error

Hi,
I tried this driver but the VL53L0X_example.py
doesn't work property.
this is the output:

**L53L0X Start Ranging Object 0 Address 0x29

VL53L0X_GetDeviceInfo:
Device Name : VL53L0X ES1 or later
Device Type : VL53L0X
Device ID : VL53L0CXV0DH/1$1
ProductRevisionMajor : 1
ProductRevisionMinor : 1
Call of VL53L0X_PerformRefCalibration
API Status: -6 : Range error
Timing 20 ms
Call of VL53L0X_StopMeasurement
Wait Stop to be competed
API Status: 0 : No Error**

Why is it unable to read the distance?
