What version of .NET does your existing project use?

.NET 6

What version of .NET are you attempting to target?

.NET 8

Description

Have a .NET 6 in-proc function that was migrated to .NET 8 isolated using the migrration guide: https://learn.microsoft.com/en-us/azure/azure-functions/migrate-dotnet-to-isolated-model?tabs=net8

The function works locally and no issues were present before in Azure, but now it shows these errors despite seeming to function as expected:

@carsongaddgmr What deployment method are you using? Does it work when deploying through another method, such as core tools?

carsongaddgmr commented 1 month ago

@kshyju It is being deployed through pipelines. I attempted to publish through the Azure CLI using core tools, but encountered an SSL connection error. I was able to publish through VS and one of the instances of the error went away, but the primary error still remains.
