MsalClientException on calling acquireTokenSilentAsync #18
Description
Hi,
I am using 'com.microsoft.identity.client:msal:0.2.+' in my Android application with B2C configuration.
It is working as expected when I was trying to login using com.microsoft.identity.client.BrowserTabActivity with my credentials and I am also getting my accessToken successfully to use for my server calls.
Before making any server call I am calling acquireTokenSilentAsync method to make sure the existing access token is not expired and also to get new token in case of its expiry. The method is returning same token in its call back response AuthenticationResult as long as it is not in expired.
But the problem here is, once the token got expired I am not receiving a new token. Instead receiving an exception saying
java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $
Any help would be appreciated. Thank you.
For more info the below is the Kotlin code that I am using to get new token silently
fun getMSALAuthTokenSilently(){
var accounts = App.loginClientAppContext?.accounts
accounts?.let {
App.loginClientAppContext?.acquireTokenSilentAsync(arrayOf(App.appContext?.resources?.getString(R.string.redirect_uri_scope)), it[0], object : AuthenticationCallback{
override fun onSuccess(authenticationResult: AuthenticationResult?) {
//Storing ACCESS_TOKEN into preferences
authenticationResult?.accessToken?.let { token ->
if (token.isNotEmpty()){
Log.d("MSALSilent token succ:", token )
}else{
Log.d("MSALSilent token error:", "token is empty" )
}
}
}
override fun onCancel() {
Log.d("MSALSilent token error:", "cancelled" )
}
override fun onError(exception: MsalException?) {
when (exception) {
is MsalClientException -> {
/* Exception inside MSAL, more info inside MsalError.java */
Log.d("MSALSilent token error:", "MsalClientException "+exception?.message )
}
is MsalServiceException -> {
/* Exception when communicating with the STS, likely config issue */
Log.d("MSALSilent token error:", "MsalServiceException "+exception?.message )
}
is MsalUiRequiredException -> {
/* Tokens expired or no session, retry with interactive */
Log.d("MSALSilent token error:", "MsalUiRequiredException "+exception?.message )
}
}
}
})
}
}
