When i started to set up this blog (based in ghost), i put a bunch of sensitive data in environment variables in the heroku configuration.
The problem was a key of google drive API, the content is multi-line and can’t make it work in one line. When i put the new line character in the string
\n, this wasn’t interpreted by node.
The only solution that i found for this problem was the next one, convert the string to a buffer and then to string again.
