Thanks for informing will check and confirm the same.

I checked it seems fine.can you try again else share your code also.

[anime-shed]

I'm sorry, it's a private project, so I won't be able to share the code. I can provide snippets that may help you debug the cause.

I tried to try again on my project, but for some reason, I am facing:

[2024-05-28T15:16:31.037Z] Found Using for user secrets file configuration.
[2024-05-28T15:16:32.849Z] No job functions found. Try making your job classes and methods public. If you're using binding extensions (e.g. Azure Storage, ServiceBus, Timers, etc.) make sure you've called the registration method for the extension(s) in your startup code (e.g. builder.AddAzureStorage(), builder.AddServiceBus(), builder.AddTimers(), etc.).
[2024-05-28T15:16:32.899Z] The 'FUNCTIONNAME' function is in error: The binding type(s) 'blobTrigger' are not registered. Please ensure the type is correct and the binding extension is installed.
For detailed output, run func with --verbose flag.

I am also having the same issue after upgrading from .Net 6 to .Net 8.

Microsoft.Azure.WebJobs.Script: Error building configuration in an external startup class. FileNetWorkFlows.Workflows: Could not load file or assembly 'Microsoft.Extensions.Configuration.Abstractions, Version=8.0.0.0

I even attempted adding that package to the project explicitly.

@dsgb1987, will it be possible to share your code snippet for @bhagyshricompany since I am facing an error on my end?
