Debugger doesn't load when there is a closure in Yii::trace

[yii-bot]

This issue has originally been reported by @guidebin at yiisoft/yii2#8550.

The debug view wasn't loading and it took me a while to figure out why. In the log it was showing:

[warning][yii\log\Dispatcher::dispatch] Unable to send log via yii\debug\LogTarget: Exception 'Exception' with message 'Serialization of 'Closure' is not allowed'

I finally found out it was caused by using Yii::trace with a closure, removing the trace call fixed it. Looks like the same issue as #5402, which was fixed previously.

confirmed for Yii::info(). Its causes skipping of i.e. a POST request in the debug log too.

thought we had fixed this long ago. does not seem to be the case for all situations.
