Same origin & destination, but different time => no coverage. Why? How can I fix this? (HERE Transit API v8 )

Question

I've been working on a project which utilises the HERE Transit API v8. Unfortunately, for some reason, the API seems to return the following error. The strange thing is, I've tried the same exact API call (same destination, same origin) but only changed the arrival_time by like 10 minutes and it suddenly started/stopped working.

{'notices': 
[
{'title': 'Routing is not possible due to missing stations in a given range', 'code': 'noStationsFound'}, 
{'title': 'Route between origin and destination is not possible given current input parameters', 'code': 'noRouteFound'}, 
{'title': 'This notice is deprecated, see noRouteFound', 'code': 'noRoutesFound'}
], 
'routes': []}

To give an example, the following worked:

origin: 49.1922443,16.6113382
destination: 50.0777015686,19.7847995758
arrivalTime: 2022-09-10T06:00:00.000Z

But the following didn't work:

origin: 49.1922443,16.6113382
destination: 50.0777015686,19.7847995758
arrivalTime: 2022-09-10T06:10:00.000Z

Answer 1

As told by Park, there is no public transit for arrival time from 2022-09-10T06:10:00.000 to 2022-09-10T07:00:00.000Z to get the destination
