We’re still seeing this in MiniProfiler 0.1.27.

Usually after a longer wait time where the local development server is not running (say overnight) this will crop up the next morning:

!! Unexpected error while processing request: No such file or directory - /Users/user/code/project/tmp/miniprofiler/mp\_views\_3b8d0774d3f759f36dd96f694bb39df4

This is likely happening due to purge rules, we only keep data around for 24 hours see:

Open to have a PR that makes this more configurable.
