Error Handling
When you make an API call to access an HMS SDK, the SDK may return error codes. ErrorCodes are usually returned when a problem that cannot be recovered without app intervention has occurred.
These are returned as type='error' through the notifications interface. The type of notification.data is HMSException. Find the HMSException interface here.
Handling Autoplay Error
Most browsers have a restriction on audio autoplay where audio is allowed only if the user has interacted with the page. You can read more about the restrictions here for chrome and safari.
If an autoplay error is received(code=3008), UI can show a popup or a notification with button. Once a user click has happened confirming an interaction point, unblockAudio can be called.
await hmsActions.unblockAudio();

Following are the different error codes that are returned by the SDK. Before returning any error code, SDK retries the errors wherever possible.
