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