Hi,
are you sending custom object/data with the login response? If so can you show us the relative code?

Thanks

Can you please post an excerpt of your server side Extension, showing the login response?

Ps: we use custom SFSLoginException

SFSErrorData sfsErrorData = new SFSErrorData(SFSErrorCode.GENERIC_ERROR);
sfsErrorData.addParameter("{ \"ErrorCode\" :-1, \"error_message\" :\"Unkown\" }");
throw new SFSLoginException("Error Message",sfsErrorData);

I can see this exception on backend side console, but Client can not parse correctly on WebGL platform. ( No problem Android,ios )

You can't send that error message as a JSON string. Instead of a generic error, send a specific error (for example SFSErrorCode.LOGIN_BAD_USERNAME) passing the expected parameters (in the example, the wrong name).
On the client side you will get a composed error message based on the parameters you sent and the error type.
See this link for the server side example: http://docs2x.smartfoxserver.com/Gettin ... wtos#item3
and this link for the client side error message customization: http://docs2x.smartfoxserver.com/Advanc ... r-messages

If I can not use sfsErrorData.addParameter function with JSON data . How can I send GENERIC_ERROR with additional SFSObject data ? Because I need to send addictional data with login error.

You may "url encode" data. For example:

Code: Select all

"{'some':'object', 'list':[1,2,3,4]}"

becomes

Code: Select all

'%7B%27some%27%3A%27object%27%2C+%27list%27%3A%5B1%2C2%2C3%2C4%5D%7D’

You can then decode the string on the client side and convert it back to an object.
