Getting error message on new project

Pontoon
#1

This is my first time using Pontoon and heroku so I assume any of my question could be interpreted as dum by advance users, but that’s just me learning …

So on my recently deployed heroku app I would like to add a new project. I fill the form as followed:

type = "git"
url = "git@github.com:12rambau/sepal_ui.git"
path_to_toml_file = "l10n.toml"
repository = "https://github.com/12rambau/sepal_ui"

the other parameters are unrelevants.
When I click on sync nothing happens but the when I check the logs I see the following error:

Can somenone explain me what if the problem is coming from my repository or from my app configuration ? Even better if you can explain what I need to change that would be amazing.

#2

That seems to come from https://github.com/jaysonsantos/python-binary-memcached/blob/b894f0c1502283aa4b6bd983316c4b7c798545c0/bmemcached/protocol.py#L275, which indicates that you might have an authentication problem

#3

thanks for the link. What I was expecting is the error above (“Incorrect username or password”). The one I’m getting is the more generic one unfortunatelly and does not provide any information on the actual problem from pontoon side.

Let’s go one step prior in the ssh config of my app:

SSH_CONFIG:

StrictHostKeyChecking=no

Host github.com
User git

and SSH_KEY is an ed25519 key generated as suggested by Github. It is registered on my github account and working on my mac.

should I change something there ? should I replace “git” in user ? should I use a different key type ?

PS: I’m working with an app generated from the deploy to heroku button from the doc

#4

ok so moving forward, the problem was not coming from Pontoon but Heroku, after 30 days of inactivity MemCache is deactivated. I started it back from the console and I now face the following issue that seems more related to the SSH key:

Everything seems to work now or anyone getting here someday:

  • check that the memchache add-on is running
  • check that the ssh-config is set
  • use RSA key, the ed25519 is not yet supported
