exception: Activation access violation. A non-activation thread attempted to access activation services

My grain sometimes displays an error like this

System.InvalidOperationException
HResult=0x80131509
Message=Activation access violation. A non-activation thread attempted to access activation services.
Source=Orleans.Runtime

StackTrace:
at Orleans.Runtime.GrainRuntime.g__ThrowMissingContext|20_0()
at Orleans.Runtime.GrainRuntime.CheckRuntimeContext(IGrainContext context)
at Orleans.Core.StateStorageBridge`1.get_State()
at Orleans.Runtime.PersistentStateFactory.PersistentStateBridge`1.get_State()

Any thoughts? Thank you in advance.

Start with the stack trace at Orleans.Runtime.GrainRuntime.CheckRuntimeContext, then follow StateStorageBridge.State and PersistentStateFactory.PersistentStateBridge.State. Reproduce the intermittent grain error and determine which non-activation-thread access triggers it; done means the cause and a verified fix or clear usage guidance are documented.
