the error sometimes happens also by moving waypoints. Then it shows

ERROR:
<class 'owslib.util.ServiceException'>
The data corresponding to your request is not available. Please check the times and/or path you have specified.

Error message: The truth value of an empty array is ambiguous. Use `array.size > 0` to check that an array is not empty..
Hint: Check used waypoints.
