Closes #6090
Problem
The
prettyLoggerBrowserwas passing the error as a string toconsole.errorviaCause.pretty(...), which causes the browser to lose the reference to the originalErrorobject and therefore can't resolve source maps.Solution
Pass the actual
Errorobjects alongside the formatted string usingCause.prettyErrors(cause), so the browser DevTools can resolve source maps correctly.Before
After
Note
The current output shows both the formatted string from
Cause.prettyand the_PrettyErrorobjects, which results in the stack trace appearing twice.I'm open to feedback on the preferred approach:
Errorobjects — cleaner output, similar to the workaround shown in the issueHappy to adjust based on maintainer preference!
