Demo App crashes when dock icon is clicked when there are no open windows

zishanj · April 1, 2020, 7:42pm

I have handled activate event to reopen window when user click on dock icon when there are no opened windows but the app crashes with error:

Electron[16724:13128485] -[_CFPasteboardCache removeAllObjects]: unrecognized selector sent to instance 0x7f9b674b6f70

app.on('activate', () => {
      if (BrowserWindow.getAllWindows().length == 0) {
        createWindow();
      }
    });

Hi zishanj,

Thanks for the post. What is the SDK version you are using and is this happening on Windows or Mac(Or both?)

zishanj · April 2, 2020, 4:33am

SDK Ver: 4.6.15088.0210
Mac: Catalina 10.15.3
Electron: 8.2
Node: 13.2

Hi zishanj,
Thanks for the reply. We tried to reproduce this issue with the same versions that you are having but no luck. The interface createWindow is not an SDK interface, and it is hard to tell whether this issue is related to our SDK based on the provided info. If you could let us know the steps to reproduce this with our demo app or provide the SDK log for further investigation, it would be helpful.

Thanks!

Actually I have modified the code a bit to automate the 3 startup screens; domain screen, sdk screen, login screen. Instead of showing their windows I have used this directly:

functionObj['setDomain']('https://www.zoom.us', false);
functionObj['sdkauth']('my_key', 'my_secret');
functionObj['login']('my_username', 'my_password');

Hi zishanj,

Thanks for the reply and thanks for the information. Based on the info:

functionObj['setDomain']('https://www.zoom.us', false);
functionObj['sdkauth']('my_key', 'my_secret');
functionObj['login']('my_username', 'my_password');

These 3 steps need to be running in order, they cannot run simultaneously. Please have a try with the following:

setDomain -> if the setDomain success, proceed to SDKAuth
Perform SDKAUth -> if the SDKAuth success, proceed to login; Please note that the SDKAuth is an async behavior, you should only go to login page if the SDK auth is success

Please have a try and hope this helps. Thanks!
