Error handling

​​ Exceptions

An exception thrown by an RPC method implementation will propagate to the caller. If it is one of the standard JavaScript Error types, the message and prototype’s name will be retained, though the stack trace is not.

​​ Unsupported error types

• If an AggregateError Open external link is thrown by an RPC method, it is not propagated back to the caller.
• The SuppressedError Open external link type from the Explicit Resource Management proposal is not currently implemented or supported in Workers.
• Own properties of error objects, such as the cause Open external link property, are not propagated back to the caller
