vehicle_data endpoint does not return the cached data if the car is asleep

New problem today: vehicle_data endpoint does not return the cached data if the car is asleep

Seeing the same behaviour.
The workaround for now is call vehicle_data only when car is online.
If car is not online, you can wake the car up first, then vehicle_data will work.

Tesla documentation says this about vehicle_data:

Makes a live call to the vehicle. This may return cached data if the vehicle is offline. For vehicles running firmware versions 2023.38+, location_data is required to fetch vehicle location. This will result in a location sharing icon to show on the vehicle UI.

Not sure if this is a temporary problem that will get reverted or it's a permanent change.

Being able to retrieve the data without waking the car is an important feature. This happened about a month ago also but was fixed after one day. I hope this is a temporary glitch.

@derekargueta , @sethterashima can you please indicate if this is a bug or cached data won't be returned anymore?
I wish there was more heads up wrt to changes like this so that developers can handle it more gracefully. No response from the fleet support email either.

This is a documentation issue. We should fix.

This is a documentation issue. We should fix.

The server used to return the cached data just like the documentation says. So, I don't think this is a documentation issue. Are you saying that the behavior has changed and cached data is no longer returned?
