uncaught exception: abort(132) WebGL

Hello everybody!
I create a project under webgl, and sometimes I have a bug that stops my game. The error does not always appear and only when the project is started.
Full text error:

If this abort() is unexpected, build with -s ASSERTIONS=1 which can give more information.

Before this error, I see the message in the console: IndexedDB is not available. Data will not persist in cache and PlayerPrefs will not be saved.
