same issue here

same here. going back to 0.8.1 brings up a syntax error. can't get login screen to work.

Encountering this issue as well, used the one-click heroku deploy link in the readme.

Of possible note: the first person to sign-up to this channel via slackin seems to have done so without any issues. All following attempts are resulting in errors.

I'm using slackin on my own server and this change fixes the issue for me, if anyone else needs it in the meantime:

diff --git a/lib/assets/client.js b/lib/assets/client.js

Worked fine for me. Thanks @nbolt !

Yes, the fix works for me too. Should be rolled in to a new release.

I have the same issue with Slackin version 0.8.3 even after applying the fix which changes var channel = form.elements['channel'];to var channel = form.elements['channel'] || {}; in the file ~/.npm-global/lib/node_modules/slackin/lib/assets/config.js

When adding an email to the list the following error does still occur:

PRs welcome!

Oh and where does Slackin log to? My above mentioned error (undefined value) was not visible in Slackin console output on the server.

@nbolt thanks - that worked for me on 0.8.3
