A bit after doing vulcan create, I look at the logs using heroku logs and this is what I see:

I've seen both:

2012-04-18T23:44:31+00:00 app[web.1]: undefined:0
2012-04-18T23:44:31+00:00 app[web.1]:

@ddollar

This error probably means that your account is not verified and you were unable to add the cloudant addon. You can try manually doing heroku addons:add cloudant -a YOUR_VULCAN_APP_NAME. I'll make this error more obvious.

@ariofrio

My account is verified. When I run heroku addons:add cloudant -a YOUR_VULCAN_APP_NAME, I get this:

-----> Adding cloudant to MY_VULCAN_APP_NAME... failed
! Add-on already installed

@ddollar

For some reason it thinks your CLOUDANT_URL is invalid:

@bergie

Having the same issue

$ heroku addons:add cloudant -a MY_VULCAN_APP_NAME

@ddollar

What command are you using to run vulcan?

For some reason it's choking on parsing your deps: https://github.com/heroku/vulcan/blob/master/server/web.js#L56

I can't seem to reproduce this locally. You could consider cloning your vulcan app locally and adding some debugging statements around the deps stuff to figure out what's going on.

@ddollar

Is it possible you're using an older version of vulcan to run vulcan build than you used to vulcan update ?

@bergie

I have vulcan as installed with gem install vulcan. I'm running simply:

$ vulcan build -v -o $TEMPDIR/libgda-$LIBGDA_VERSION.tgz

so no deps provided in this case.

@bergie

I made the following change:

    var deps = [];
    if (fields.deps) {
      deps    = JSON.parse(fields.deps);
    }

And now it seems to at least store to CouchDB:

@ddollar

If you submit that as a pull request, I'll merge and release a new version.

@ddollar

Released as vulcan 0.6.1, thanks!

@yaniv-aknin

My newly created vulcan server kept failing similarly to how this issue describes. After some digging in, I saw that heroku addons:add cloudant -a my-vulcan-server outputs:

Adding cloudant on vulcan-fusic... failed
 !    Could not create resource with vendor, please try again later

I'm guessing the issue is with cloudant, but I think vulcan should be able to better handle this condition and report it in a more meaningful manner than a traceback.
