Migrating to self hosted Parse Server isn't giving me the logged user - parse-server

Question

I'm trying to migrate my Parse server to my own server instance in DigitalOcean. After deploying my parse-server I'm falling in some issue I can't understand.
When you make a call to the Cloud Code, you can retrieve your user as request.user if you have revocable sessions enabled.
Everything is OK, but sometimes (random times) I get this strange behaviour: my request.user doesn't appear in Cloud Code.
I thought it could be a bad session token so I got rid of it by doing:
if (!request.user) {
response.error("INVALID_SESSION_TOKEN");
return;
}
and obbligate the user to log-in again.
This wasn't working, I was getting an INVALID_SESSION_TOKEN everytime I log in, so I decided to debug. These are my steps:
1.- Log in my user, so a _Session object is created:
so the sessionToken is r:a425239d4184cd98b9b693bbdedfbc9c
2.- Make call cloud function (sniff log):

3.- request.user is still not appearing on CloudCode.
EDIT: Reseting the parse-server worked in this case, but not in some others.

Days ago I got the solution.
When you have successfully deployed your Parse server, you will get request.user from any end point of the cloud, but if you call a cloud function from cloud, you won't get this request.user at least you pass the sessionToken:
Parse.Cloud.define("foo", function(request, response) {
if (!request.user) {
response.error("INVALID_SESSION_TOKEN");
return;
}
var countResponses = 0;
var responsesNeeded = 1;
Parse.Cloud.run('bar', request.params, {
sessionToken: request.user.getSessionToken(),
success: function(c) {
countResponses++;
result = c;
if (countResponses >= responsesNeeded) {
response.success(result);
}
},
error: function(error) {
response.error(error);
}
});
});
in this case, foo will have request.user and bar won't, unless you pass sessionToken.
