--------------------------------------------
Summary: camel-slack: incorrect handling of error responses
Key: CAMEL-15326
URL: https://issues.apache.org/jira/browse/CAMEL-15326
Project: Camel
Issue Type: Bug
Components: camel-slack
Affects Versions: 3.4.2
Reporter: Otavio Rodolfo Piske
Attachments: log-when-channels-read-is-missing.txt
The consumer on the camel-slack component is not checking for error responses
coming from the Slack API. Under some circumstances this can be problematic and
hide messages that would be helpful for the user to diagnose problems on
his/her setup of the app/bot account.
One example that causes this problem is when the user creates a bot and does
not give the bot the channels:read scope/permission. In this case the component
throws a NullPointerException because it looks for an element on the json
response that does not exist.
It seems it can also happen when trying to read the channel messages without
the channels:history scope, although, in this case the component does not throw
any exception.
