iOS Safari bug with Websockets about speech-javascript-sdk HOT 13 CLOSED

Hi @ddddm, let me look into this and talk to the team and get back to you.

@daniel-bolanos Is this something you're aware of?

from speech-javascript-sdk.

Hey @ddddm - can you get me a complete copy of the headers? In my testing, I'm not seeing any content-type header set at all, but I'm not testing on an iOS device.

I have a suspicion that the long URL may be part of the issue. The Watson service also accepts the token in a X-Watson-Authorization-Token header or in a cookie - is it possible to set either of these in Cordova / iOS Safari?

from speech-javascript-sdk.

@nfriedly yes, I remember this issue, there was a thread about it with more details, I wish I could find it...

Yeah sure @nfriedly!

I can't give you headers from iOS because the request never happened according to Safari DevTools:

But the error exists:

From an android device, I have this request details (might help?)

Hum.. I had checked in firefox and I didn't see that but now that I'm trying in chrome, I also see the empty Content-Type header. I think either the service is sending different headers (unlikely) or firefox is not correctly displaying the empty header.

@daniel-bolanos is this something that the team can take a look at - either not creating a content-type header at all, or else setting it to something like application/json?

from speech-javascript-sdk.

Can this be related to the problem where the (authorization token) > max safari url length ??

from speech-javascript-sdk.

That might be a problem too @germanattanasio, but the service does appear to be sending an odd, perhaps even invalid header which we should probably handle first.

from speech-javascript-sdk.

@nfriedly @daniel-bolanos any updates on this?

from speech-javascript-sdk.

I believe the service team will remove the empty content-type header in an upcoming release, but I'm not sure of the timing.

This is now fixed, https://watson-speech.mybluemix.net/file-url.html shows an example that should work on mobile Safari

The same websocket error is throwing for me also when running ionic app in iphone device.

the error is.
failed: Failed to send WebSocket frame.

is there any solution. Please help me to solve this issue

from speech-javascript-sdk.

@Dinesh93 That is actually a different bug, and one that is outside of our control: #40

The code is fixed in webkit core, and it works in the latest preview builds of Safari 11 (on desktop and, I assume, on iPhone). Expect it to be released in a month or two, whenever Apple puts out the next major releases of macOS and iOS.

If you need a faster solution, you can use our Swift SDK to build a native (non-ionic) app: https://github.com/watson-developer-cloud/swift-sdk
