No callbacks when using KalturaClientDelegate

[adeelmiraj]

In my project I have to make multiple calls to my Kaltura Server and those calls cannot be synchronous as it would damage the user experience. Now the issue is when I use the Singleton design pattern the KalturaClientDelegate works as expected. But I use a separate KalturaClient instance for some server calls. In those cases I do not get any delegate method callbacks.

Here are some notable points that may help understand the problem:

1. Synchronous calls always work
2. Asynchronous calls (aka KalturaClientDelegate mehods) work if I use KalturaClient in a singleton object
3. If I create a new instance of KalturaClient then the asynchronous calls do not work

The sample code looks like this:

let config = KalturaClientConfiguration.init()
let logger = KalturaNSLogger.init()
config.logger = logger
config.serviceUrl = KalturaBaseURL

let client = KalturaClient.init(config: config)
client?.ks = KalturaSessionToken
client?.delegate = self

let categoryList = client?.category.list()
print(categoryList.totalCount)

If I comment out the client?.delegate = self line then I receive the response.

Here's the implementation of the delegate protocol.

func requestFinished(_ aClient: KalturaClientBase!, withResult result: Any!) {
    print(result)
}

func requestFailed(_ aClient: KalturaClientBase!) {
    print(aClient.error.localizedDescription)
}

Hi @adeelmiraj,

Thank for you reporting an issue and helping improve Kaltura!

To get the fastest response time, and help the maintainers review and test your reported issues or suggestions, please ensure that your issue includes the following (please comment with more info if you have not included all this info in your original issue):

• Is the issue you're experiencing consistent and across platforms? or does it only happens on certain conditions?
  please provide as much details as possible.
• Which Kaltura deployment you're using: Kaltura SaaS, or self-hosted?
  If self hosted, are you using the RPM or deb install?
• Packages installed.
  When using RPM, paste the output for:

	# rpm -qa \"kaltura*\"

For deb based systems:

	# dpkg -l \"kaltura-*\"

• If running a self hosted ENV - provide the MySQL server version used
• If running a self hosted ENV - is this a single all in 1 server or a cluster?
• If running a self hosted ENV, while making the problematic request, run:

	# tail -f /opt/kaltura/log/*.log /opt/kaltura/log/batch/*.log | grep -A 1 -B 1 --color \"ERR:\|PHP\|trace\|CRIT\|\[error\]\"

and paste the output.

• When relevant, provide any screenshots or screen recordings showing the issue you're experiencing.
