Overleaf: "user:create-admin" task: user.save is not a function

[tacruc]

Hi,
I'm trying to add an admin user and it might be, that the email is already existing as normal user.
docker exec sharelatex /bin/bash -c "cd /var/www/sharelatex; grunt -vv user:create-admin [email protected]"

I get the following error:

Running "user:create-admin" task
the options [appname] is not supported
using statsd

Fatal error: user.save is not a function

I think the error is in this line:
https://github.com/overleaf/overleaf/blob/7b2238ae584a38f29852d26f8c36db9f04468861/tasks/CreateAndDestoryUsers.coffee#L21

Yes, the problem is that such user already exists, the error message should be improved.

Is there a way to turn an existing user into an admin.

You can set the isAdmin property in the DB:

$ docker exec -it mongo mongo
> use sharelatex
switched to db sharelatex
> db.users.update({email: '[email protected]'}, {$set: {isAdmin: true}})

You might need to restart sharelatex container after that.
