400 errors for half my tiles in Map Tiles API

Question

I have this error below for about half of my tiles (see screenshot). What can be wrong. It used to work just fine. I haven't made any edit related to the API to my scene. From my understanding, the issue happened overnight. Why does it happen and how may I fix it?

[2024-03-17 19:57:20.055] [error] 
[TilesetJsonLoader.cpp:889] Received status code 400 for tile content 
https://tile.googleapis.com/v1/3dtiles/datasets/CgA/files/UlRPVEYubm9kZWRhdGEucGxhbmV0b2lkPWVhcnRoLG5vZGVfZGF0YV9lcG9jaD04ODAscGF0aD0yMTYwNDE1MjUyNTE0MjcxNDQyLGNhY2hlX3ZlcnNpb249NixhbGlnbm1lbnRfdmVyc2lvbj1ST0NLVFJFRV85NjlfR09PR0xFX0RBVFVNXzIwMjMxMjA1VDA3NTNaX2dlbmVyYXRlZF9hdF8yMDI0MDIyMVQxMzA5Wg.glb?session=CLrnutPxmpqeahDDvdyvBg&key=xxx

I am using Unity version control, maybe something went wrong there?

Answer 1

400 is the Bad Request status code due to something that is perceived to be a client error - in other words, it's not proceeding due to something it believes is an error from your end.

If you go to the URL in your error message (as linked here), it states:

[{
  "error": {
    "code": 400,
    "message": "API key not valid. Please pass a valid API key.",
    "status": "INVALID_ARGUMENT",
    "details": [
      {
        "@type": "type.googleapis.com/google.rpc.ErrorInfo",
        "reason": "API_KEY_INVALID",
        "domain": "googleapis.com",
        "metadata": {
          "service": "tile.googleapis.com"
        }
      }
    ]
  }
}
]

This part: "message": "API key not valid. Please pass a valid API key.", seems self explanatory - it doesn't like your API key. It may be that your key expired or that an error was introduced in your source somehow. Regardless of how it got that way, it appears like your API key is the problem.

Answer 2

It can happen if your internet connection is bad or interrupted.
