Debugging JSON

[BenTheElder]

I received an email yesterday asking about debugging thread 'main' panicked at 'Error: Slack Api Error: "rtm::StartError: JSON error"', src/main.rs:67, for the example in slack_rs. I'm not aware of a particularly clean way to debug this right now, we should probably look at improving this.

I've also seen those errors last weekend - the reason in that case was that Slack was (mostly) down for half an hour or so (also the App barely worked). Perhaps the error response looked different than expected?
