Error actor instance is missing about dotnet-sdk HOT 4 OPEN

@tructran91 Several questions:

• What version of Dapr runtime are you using?
• Do you see this only in production or does it also reproduce locally?
• Have you tried using the 1.12 versions of both the Dapr runtime and Dapr .NET SDK?
• Do you have any Dapr sidecar logs (preferably with --log-level set to debug) for the period in which the error occurs?

from dotnet-sdk.

@tructran91 - This most likely means that the actor isn't hosted in your runtime. Is this the app that hosts the actor?

1.8 is quite old though, and no longer officially supported. I'd recommend updating to 1.12 and we can debug from there. Here is the list of supported version.

Thank you for your reply.

@philliphoff

• We're using version 1.11.0 of Dapr runtime, in our source code, we use Dapr.Actors.AspNetCore version 1.8.0
• It happen both production and locally, it very hard to reproduce. It not always occurs
• We use ELK to log error and info happen in system

from dotnet-sdk.

I would still recommend updating the Dapr.Actors.AspNetCore version.

Generally though, this error simply means there isn't a host available for that actor. Do you see any instances of your apps restarting? It could be that they are temporarily down and thus no longer receiving traffic. Without seeing more of your code and how you setup/register your actors though, we can't debug a whole lot more from here.
