No job functions found when adding non-primitive app setting

[slabarque]

Repro steps

Provide the steps required to reproduce the problem:

func init --worker-runtime dotnet-isolated --target-framework "net8.0" --language C#
func new --template "Timer trigger"
func start --port 7001

Function runs successfully
Now add the following appsetting in local.settings.json:

"myobj": { "key":"value"}

local.settings.json now looks like this:

{
    "IsEncrypted": false,
    "Values": {
        "AzureWebJobsStorage": "UseDevelopmentStorage=true",
        "FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated",
	"myobj": { "key":"value"}
    }
}

Now start the function again

func start --port 7001

The output is now:

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.).

I would expect this to run successfully or at least give a more clearer error message.

Just found the following in Ms docs

Values must be strings and not JSON objects or arrays. Setting names can't include a double underline (__) and shouldn't include a colon (:). Double underline characters are reserved by the runtime, and the colon is reserved to support dependency injection

Opening again, because maybe it's worth to look at the error message. I lost quite some time to figure out it was actually my local.settings.json file causing this message.

Thanks for reporting pls share func invocation id,timestamp,region etc.

The issue was with the local.settings.json file, so this occurred when testing on my local machine. See repro steps.
