You can access the debugging page in Wax LRS by clicking on the 'beaker' icon in the top right of the Wax dashboard. Debugging is available to all customers on a paid monthly Wax LRS plan.
Errors from the last 24 hours are displayed in near real-time on the debugging page. Only errors we can provide helpful feedback for will be displayed; truly unexpected errors may not be present, depending on where they happen. Right now this is mostly Experience API errors, though some errors for the Sears APIs will also appear here. The goal is to aid development, not triage production errors, though it has some use for the latter.
