I got the same error. Is there any way to resolve this issue?

[aratakokubun]

I resolved the issue. In my case, I made a mistake to input verification token to the slack token in the slack-chat atom setting. I cleared the slack token and restarted atom. Then, authentication page was opened and I got the token for slack-chat. After I input the token and restarted atom, I got to be able to use the slack-chat.
