Help me!
1

Feature(s) impacted

When I try to deploy my git directory on heroku, I get this error that I can’t solve

Observed behavior

I am at the point where I enter the heroku url to get the remote admin.

Unfortunately nothing happens as expected.

I check with the command heroku logs --tail what is going on.

I get this error that I can’t solve

Hello @MikaelMonjour,

Do you try to run your project with gunicorn on your own computer before to run it on Heroku ?
I have a similar config that run well on Heroku.

I used python3 manage.py runserver locally.

But after testing locally it cameback with the same error

$ gunicorn siteweb.wsgi

Hi @MikaelMonjour,

Ok, the init workflow seems to work with asgi but not with wsgi.
To fix your issue, move the init_forest call below the get_wsgi_application call.

#init_forest() to remove

application = get_wsgi_application()
init_forest()
5

seems ok locally ?

I am trying a push on heroku

Cannot send the apimap to Forest. Are you online?
6

You need to set the FOREST_ENV_SECRET and the FOREST_AUTH_SECRET in you heroku Environment variables.

7

The local connection does not work anymore :smiling_face_with_tear:
I do not get anything on log file :smiling_face_with_tear:

8

What did you change ? If you’re changed only the wsgi file, there are no reasons to break the local environment.
What’s happened on server start ?

9

I restart everything from scratch, it seems to work but url not responding …

Hi @MikaelMonjour, I edited your last message and removed the picture you shared as you should not share your FOREST_ENV_SECRET to anybody.

Thanks

Hi @MikaelMonjour,

Nice to see your project works!

You should removed app.forestadmin.com from the ALLOWED_HOSTS settings. As explained in the doc this variable is used to set the domain(s) that serve the django project.
