Hello!
I have a function app that uses 10 instances.
From the main orchestrator I want to start 100 sub-orchestrators in parallel. I do this using: yield context.df.task.all(...).
I get this error:

I've update the function.json with a proper name for bindings and still get the same error when I want to start 100 sub-orchestrators in parallel
"bindings": [
{
"name": "EtlOrchestrator",
"type": "orchestrationTrigger",
"direction": "in"
}

@Zava Do you have any app setting called ExternalDurablePowerShellSDK ? or are you injecting it through dependency injection?
The problem stemmed from the logic used to generate the list of sub-orchesstrators, which occasionally produced a different order.

Does that mean you were able to fix it? I'm running into the same issue, though with a different durable function workflow
