UseHttpCorrelation for function app with TimerTrigger and HttpTrigger gives Error

[HLobik63]

Describe the bug
With .net8-library Arcus.Observability.Correlation Version="3.0.0", when we have a function app which contains 2 functions, one with a TimerTrigger and 1 with a HttpTrigger, we get an error message for the first function, saying that the function doesn't have a HttpTrigger.

To Reproduce
Create a function app that contains both TimerTriggers and HttpTriggers, and add library Arcus.Observability.Correlation Version="3.0.0.

Expected behavior
Being able to use UseHttpCorrelation() within a function app that contains both TimerTriggers and HttpTriggers.

Additional context
Occurred after migrating from .NET5 to .NET8.

• Version
  Arcus.Observability.Correlation Version="3.0.0

Hi @HLobik63 , great for your use of Arcus.
The problem you're refering too, is expected behavior. The .UseHttpCorrelation() is only meant to be used in HTTP-scenarios, hence the exception.
We haven't had time to investigate in supporting Time-triggered Functions, but you're always welcome to investigate those yourself. Tip: you can still use Arcus Observability if you build on top of the .AddCorrelation(). See the correlation docs for more info.
