[I] AmberFIFOChannel.getPortId throws NoSuchElementException when called before setPortId [texera]
Yicong-Huang opened a new issue, #4818:
URL: https://github.com/apache/texera/issues/4818
### What happened?
`amber/src/main/scala/org/apache/texera/amber/engine/architecture/messaginglayer/AmberFIFOChannel.scala::getPortId` does `this.portId.get` on an `Option[PortIdentity]` that defaults to `None`. Calling `getPortId` before `setPortId` therefore throws a bare `NoSuchElementException` with no contextual message — quite different from a guard-and-raise (`require(...)`, `assert(...)`) that would point the caller at the missing setup step.
`portId` is also untyped at the API level (the public getter declares `PortIdentity`, not `Option[PortIdentity]`), so callers cannot pattern-match safely; their only options today are blind `.get` access or wrapping in a try/catch.
### How to reproduce?
```scala
import org.apache.texera.amber.core.virtualidentity.{ActorVirtualIdentity, ChannelIdentity}
import org.apache.texera.amber.engine.architecture.messaginglayer.AmberFIFOChannel
val ch = new AmberFIFOChannel(
ChannelIdentity(ActorVirtualIdentity("from"), ActorVirtualIdentity("to"), isControl = false)
)
ch.getPortId
// java.util.NoSuchElementException: None.get
```
