Is you Phabricator instance returning HTML somehow while connecting through conduit?

[glugy]

I ran into this problem as well. A simple update to the config file fixed it for me. In the legacy branch, the api setting looked like this: https://phab.domain.com/api/, in the new Go version, the api setting looks like https://phab.domain.com. If you're upgrading from the old version, be sure to take the /api off the end of your URL.

👍

Sorry how can I solved this problem?

[etcinit]

I would make sure I'm using a recent version of Phabricator and Phabulous 2.3.

Thanks, Its work now. But I also want to ask. I'm setup notice to other channel. But just channels: feed can be work?

channels:
  # The feed channel is where Phabulous will post every feed event to this
  # channel. Leave it blank to disable this feature.
  feed: '#phabricator'

  # You can map repositories to a channel. This will send feed events regarding
  # commits and revisions to the specified channel.
  repositories:
    CALLSIGN: '#channel'
    OTHERCALLSIGN: '#otherchannel'  

And response error message

In my case, this invalid character '<' looking for beginning of value was because Phabricator was returning 401 Unauthorized errors (with HTML in them). FYI.
Might wanna be more explicit about non-200 responses like this from Phab.
