WMTS Time demo has lots of 400 Bad Request errors

[mramato]

Run https://cesiumjs.org/Cesium/Build/Apps/Sandcastle/index.html?src=Web%20Map%20Tile%20Service%20with%20Time.html&label=Showcases and open the debugger and you'll see a lot of 400 Bad Request errors. Going to one of the bad urls directly results in:

<ExceptionReport xmlns="http://www.opengis.net/ows/1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://schemas.opengis.net/ows/1.1.0/owsExceptionReport.xsd" version="1.1.0" xml:lang="en">
<Exception exceptionCode="TileOutOfRange" locator="TILEROW">
<ExceptionText>TILEROW is out of range, maximum value is 2</ExceptionText>
</Exception>
</ExceptionReport>

@tfili any ideas? This happens without the new Resource stuff.

I'm wondering if the weather service only generates tiles with information. Since we don't parse the capabilities file, we just try to load every tile as if it was there even if the capabilities file says its not.

That sounds like a good explanation. If we think this is just a data issue, we can close it.

This is still a problem as of CesiumJS 1.66, no tiles get loaded in the WMTS demo.

I think the URL has since changed, which is why it currently isn't working: #8310

And this is fixed in this PR: #8352
