Undefined method `desc=' for nil:NilClass in 4.0.2

berkos opened this issue · comments

👋 It seems like 4.0.2could have introduced this potential issue where req.current_layer is nil.

NoMethodError: undefined method `desc=' for nil:NilClass
  from scout_apm (4.0.2) lib/scout_apm/instruments/typhoeus.rb:54:in `run'

It's occurs here related with #376.

System:
Rails 6.1.1
Ruby 3.0.0

Please let me know if more information is needed. 🙏

Is there a deeper backtrace on that? I'll fix it with the nil check that's needed, but curious how it happened since the start_layer call is the line just above (so there's always at least one layer).

Hi @cschneid , thanks for quick reply.

I hope this is more helpful.
