failed to get ID: %w

Error message

failed to get ID: %w

What it means

httpRequest.RequestId() invokes the underlying runtime object's 'id' method through the raw-objects bridge. The 'failed to get ID' wrapper means the bridge call itself failed before a value was returned — the runtime object could not execute its 'id' method.

Solutions

1. Ensure the httpRequest came from the library's dispatch/API pipeline, not manual construction
2. Inspect the wrapped cause (%w) for the underlying bridge failure
3. Verify the runtime/script version matches the Go client version
4. Re-dispatch the request to obtain a fresh object

if req == nil { return errors.New("request unavailable") }

func (h *httpRequest) hasID() bool { return h != nil && h.RawObject != nil && h.RawObject.Pointer() != 0 }

id, err := req.RequestId()
if err != nil {
    return fmt.Errorf("request has no ID: %w", err)
}

When it happens

Trigger: Calling RequestId() on an httpRequest whose backing raw object is invalid, detached, or lacks a working 'id' method; the runtime method raises an exception during execution.

Common situations: Reusing a request object after the script/runtime was torn down; building requests manually instead of through the library's dispatch pipeline; version drift where the runtime object no longer exposes 'id'.
