undefined is not an object (evaluating 'b.play()["catch"]'

[soypaduano]

My error reporting platform (Sentry) has recorded this error with tons of users and lot of times. I do not have the way to reproduce it but I do have information about when it happens.

browser: Mobile Safari UI/WKWebView 9.3.5
browser.name: Mobile Safari UI/WKWebView
device: iPad
device.family: iPad
handled: yes
level:error
mechanism: instrument
os: iOS 9.3.5
os.name: iOS
ip:83.52.69.83

The line and context:

That would correspond to this line in the source code:
https://github.com/google/blockly/blob/master/core/workspace_audio.js#L119

The good news is that this error will have no significant effect on the end user. The worst case scenario is that a sound (like the 'click' when connecting blocks) is failing to preload and will thus play slightly late the first time it is used.

It's this bug: #299

Cross browser sound is really hard. We need to spend some time looking at this again (#3536).

@NeilFraser Yeah, the good thing is that the user is not blocker. I was just scrolling through my errors on Sentry and that one is common. Thanks for the reply.

I wasn't able to repro this on IOS 9.3.5

This may have been fixed in #2614
@soypaduano have you still been seeing this issue and what version are you on?

[moniika]

Closing under the assumption that it has been fixed.
