Hi Tobiak,

Thanks for using Zoom SDK. The error code 150 means “Invalid Arguments”, the following 3 scenarios will trigger this error:

1. If the `paramDict` is null or not valid
2. If the meeting number is null or not valid(e.g: has length 0)
3. If the domain(kSDKDomain) is null or not valid(e.g: has length)

The code snippet looks good, but I would suggest checking the above 3 scenarios. For #3, if the SDK is not proper initialized, then the domain will be invalid and get this error.

Hope this helps. Thanks!

Thanks, I had to initialize sdk this way;

[MobileRTC initializeWithDomain:kSDKDomain enableLog: **NO**];

in my AppDelegate.m and I can join a meeting now.

I like to collect individual user names and parse along with “meetingNo” to “NSDictionary \*paramDict” at the point of “joinMeeting”. I don’t want to use the static/literal specified as …#define kSDKUserName @“Superman” in MainviewController.h (for instance).

Any help or suggestion for this?

Thank you.

Hi,  
Thanks for the reply and glad to hear that the problem was resolved.

Regarding your follow up questions:

- The `#define kSDKUserName @"Superman"` and all other static values are for demo purpose. We do not recommend hardcode anything in your code as well. Please see our disclaimer on this(We also have this in our doc):[https://github.com/zoom/zoom-sdk-ios#disclaimer](https://github.com/zoom/zoom-sdk-ios#disclaimer)
- All parameters in the `NSDictionary *paramDict` are expecting `NSString*` values, thus as long as you pass the right data type values to the `paramDict`, the way of how you collects the values are pretty flexible. For example, you can ask the user to fill a form to collect the username and meeting number(like what we have in the demo) or you can get the data from you server, etc.

Hope this helps. Thanks!
