google auth1 to oauth2 migration: Invalid authorization header - ruby-on-rails

Question

I've a script to migrate from google oauth1 to oauth2 using oauth gem
everything seems right and i can't detect any problem with the headers but it still responding with: Invalid authorization header.
Here're the headers:
opening connection to accounts.google.com:443...
opened
starting SSL for accounts.google.com:443...
SSL established
<- "POST /o/oauth2/token HTTP/1.1\r\nContent-Type: application/x-www-form-urlencoded\r\nAccept-Encoding: gzip;q=1.0,deflate;q=0.6,identity;q=0.3\r\nAccept: /\r\nUser-Agent: OAuth gem v0.4.7\r\nContent-Length: 193\r\nAuthorization: OAuth oauth_consumer_key=\"mykey.com\", oauth_nonce=\"LdBeaxxxxxxxxxxxxxxIxgd03U1DHYbs\", oauth_signature=\"wXIuxxxxxxxyxxxxj0%3D\", oauth_signature_method=\"HMAC-SHA1\", oauth_timestamp=\"1416497830\", oauth_token=\"1%2F9G2sKmQxxxxxxxxxxmDXbqqifoRBGUAii-D5sw2o\", oauth_version=\"1.0\"\r\nConnection: close\r\nHost: accounts.google.com\r\n\r\n"

and here's the code:
oauth1_consumer_key = "mykey"
oauth1_consumer_secret = "Gxxxxxxxxxxxxxxxxqb8"
# OAuth 1 - User Token / Secret.
oauth1_token = '1/9G2xxxxxxxxxxxxxxsw2o'
oauth1_secret = 'a-xxxxxxxxxxxxxxxmqG'
# OAuth 2 - Application ID / Secret
oauth2_client_id = "the_id"
oauth2_client_secret = "C-xxxxxxxxxxxxxxxxV"
# Migration Parameters.
params = {
"grant_type" => "urn:ietf:params:oauth:grant-type:migration:oauth1",
"client_id" => oauth2_client_id,
"client_secret" => oauth2_client_secret,
# "oauth_signature_method" => "HMAC-SHA1"
}
# Create the consumer object.
consumer = OAuth::Consumer.new(
oauth1_consumer_key,
oauth1_consumer_secret,
:site => 'https://accounts.google.com',
:scheme => :header
)
# Create the access token object.
access_token = OAuth::AccessToken.new(consumer, oauth1_token, oauth1_secret)
resp = access_token.post(
"/o/oauth2/token",
params,
{ 'Content-Type' => 'application/x-www-form-urlencoded' })
if resp.code.to_s != "200"
# Raise an error.
raise "#{resp.code} - #{resp.body}"
end
Any ideas?

After updating the oauth gem, I tried it again and it worked.
