If a very long stack trace got truncated, the closing triple apostrophe will be missing, thus the stack trace shows as a normal, very long message instead of a block of code.
Update:
In the picture though, it appears that the message got truncated although it is only about 1,500 characters

Technically, Slack has 40,000 characters limit, so anything beyond that got truncated. https://api.slack.com/changelog/2018-04-truncating-really-long-messages
