Hello, could you please be more specific about your problem?

[usmanhashmi2123]

i have having similar problem. In Registration Response class there is inner class card_data which has some fields.

When i post request for login with required credentails. in response cars_data field is empty.

and i am getting this error message: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 932 path $.data.card_data error detail: parseError

how can this be handled?

RESOLVED:

i was posting card_data as null object. but server was sending empty string in response

so that's why parsing issue occurred.

now server is sending empty array.issue resolved
