Troubleshoot Slack

The following table presents solutions to common issues with the Slack integration. For additional help, see the Slack developer docs.

Issue
Cause
What to do

A message failed with the channel_not_found error.

The channel doesn't exist, or it does exist but it's private.

Confirm the channel exists. If it's a private channel, run /invite @Kizen inside it.

A plain-text message was truncated.

The message exceeded 40,000 characters.

Reduce the length of the message.

A block message wasn't posted.

The JSON objects that make up the blocks might be malformed, or the blocks might exceed Slack's character limits.

Review the blocks, and try again.

You no longer have a connection to the Slack API.

The access token is no longer valid.

Re-authenticate the integration.
