What happened?

Same as discussed here.

Was able to workaround it, but we really should try to see where this unhandled promise is being thrown

Reproduction steps

1. 3D Tileset
2. Zoom in and move a little bit fast to perform a lot of requests

Sandcastle example

No response

Environment

Browser: Android CesiumJS Version: 1.117.0 Operating System: Tried with Android 11, 13 and 14

Thanks for the report @lmarcelocc! Would you be able to include a Sandcastle example that replicates the issue? That would help us give us more context to determine the issue.

Hi @ggetz ,

Unfortunately I tried last week to replicate on Sandcastle, with same 3D data, but I was not able to. Probably because, like mentioned here, could be Angular related (zone.js).

Got it, thanks @lmarcelocc. From the discussion, it looks like zone.js is wrapping native promises leading to the adverse behavior. I'm not sure there is much we can do in that situation.

We are generally trying to track down instances of undefined being thrown, as this can cause issues in our unit tests. Hopefully that will fix the issue your seeing as well.

I'm going to close this issue as am not sure there is actionable path beyond what we would do to fix #11958. Let me know if you think otherwise.
