Database Migration Problem on Heroku

[Syirrus]

Rocket.Chat Version: 0.53.0
Running Instances: 1
DB Replicaset OpLog: Disabled
Node Version: v4.7.3
Database Migration: 90

I was previously running version 0.53 and when to upgrade to the latest on Heroku 0.54.2.
I encontered an error in Heroku and decided to try to build the rocket.chat again. It succeed. However, when I went to start my dyno it kept crashing with the following error:

Updating process.env.MAIL_URL

Any idea on how to fix this? I tried unlocking with the command:
db.migrations.update({_id: 'control'},{$set:{locked:false,version:90}})
but it didn't work. I was able to migrate back to my previous version. Any ideas? Could this be related to some of the problems people are experiencing here:

By problem I mean not the DB issue, but the initial fail to build on Heroku which lead to a DB issue:

Issue: 6452
Issue: 6444

UPDATE:
After the commits from last night (roughly 120 since yesterday morning), I was able to success build on Heroku.

Did you try a fresh deployment to Heroku and even didn't get the error as described in RocketChat/meteor-buildpack-horse#10?
