Play-Framework: 2.3.x: play - Cannot invoke the action, eventually got an error: java.lang.IllegalArgumentException: - scala

Question

I am using play-framework 2.3.x with reactivemongo-extension JSON type. following is my code for fetch the data from db as below:
def getStoredAccessToken(authInfo: AuthInfo[User]) = {
println(">>>>>>>>>>>>>>>>>>>>>>: BEFORE"); //$doc("clientId" $eq authInfo.user.email, "userId" $eq authInfo.user._id.get)
var future = accessTokenService.findRandom(Json.obj("clientId" -> authInfo.user.email, "userId" -> authInfo.user._id.get));
println(">>>>>>>>>>>>>>>>>>>>>>: AFTER: "+future);
future.map { option => {
println("*************************** ")
println("***************************: "+option.isEmpty)
if (!option.isEmpty){
var accessToken = option.get;println(">>>>>>>>>>>>>>>>>>>>>>: BEFORE VALUE");
var value = Crypto.validateToken(accessToken.createdAt.value)
println(">>>>>>>>>>>>>>>>>>>>>>: "+value);
Some(scalaoauth2.provider.AccessToken(accessToken.accessToken, accessToken.refreshToken, authInfo.scope,
Some(value), new Date(accessToken.createdAt.value)))
}else{
Option.empty
}
}}
}
When i using BSONDao and BsonDocument for fetching the data, this code successfully run, but after converting to JSONDao i getting the following error:
Note: Some time this code will run but some it thrown an exception after converting to JSON

The problem is solve, but i am not sure, why this produce, I think there is problem with reactivemongo-extension JSONDao library. because when i use findOne instead of findRandom the code is run successfully, but the findRandom is run good on BSON dao. Still not found what the exact problem is that, but following is the resolved code.
def getStoredAccessToken(authInfo: AuthInfo[User]) = {
println(authInfo.user.email+" ---- "+authInfo.user._id.get)
var future = accessTokenService.findOne($doc("clientId" $eq authInfo.user.email, "userId" $eq authInfo.user._id.get)); //user findOne instead of findRandom in JsonDao
future.map { option => {
if (!option.isEmpty){
var accessToken = option.get;
var value = Crypto.validateToken(accessToken.createdAt.value)
Some(scalaoauth2.provider.AccessToken(accessToken.accessToken, accessToken.refreshToken, authInfo.scope,
Some(value), new Date(accessToken.createdAt.value)))
}else{
Option.empty
}
}}
}
