4 years ago Hi @HenriqueKraemer! Thanks for reporting this error.
I’m curious if there’s a reason you want to re-instrument the existing sql.active_record event that Rails already instruments? Do you subscribe to this event somewhere else in your codebase and therefore would like specific event information?
If you’re trying to create your own custom event, you could use a different name (reference here - "11 Creating custom events")
The reason you are seeing this error is because Rails already instruments sql.active_record and provides a payload object that it expected by our Subscriber. You can see the keys of the payload object here in the Rails codebase (for 4.2.11.1) and we expect that payload to be passed to our Subscriber.
Let us know what exactly you are trying to accomplish so we can help further. Thanks!

Describe the bug
Conflicting with others ActiveSupport::Notifications.instrument.
I have an module called CalculationPreload that I use for caclulate some data from a group of records, instead of doing one by one.
Every time that I call
execute_calculation_preloads, this error occurs:Exception message: no implicit conversion of nil into String
Error line:
ActiveSupport::Notifications.instrument('sql.active_record', name: "#{self.name} Calculation Preloads") doBacktrace:
Environment
Additional context
I have tested with older versions of ElasticAPM gem (3.3, 3.4 and 3.5), and the error was different:
Exception message: undefined method `encode' for nil:NilClass
Error line:
ActiveSupport::Notifications.instrument('sql.active_record', name: "#{self.name} Calculation Preloads") doBacktrace:
