When I switch the frontstage toTwo Viewports, an error occurs: "IModel is not open for rpc".

[JingWang111]

My code is as follows:

When viewFlag =="syncViewport", I will execute the SyncViewportProps class. However, an error occurs in the code viewState = await iModel?.views.load(defaultViewId); with the message "Uncaught (in promise) Bad Request: IModel is not open for rpc". The defaultViewId is valid and the same as the one used to load the default view.

And I have found another issue: when I comment out the onIModelConnected={_onIModelConnection} in the component, executing the SyncViewportProps class has no problems. What is the reason for this, and how can it be solved?

When defining applicationData of sync-viewport-default-content2 make sure to use a viewState property, instead of viewStateClone, i.e.: applicationData: { viewState: viewStateClone, ... }.

Other than that, based on the original error, the iModel connection is not opened.

I've added a sandbox to replicate this, but couldn't reproduce the issue (maybe I'm missing something). Feel free to fork it if needed https://www.itwinjs.org/sandboxes/GerardasB/discussion-6708

Thank you very much for your answer. The problem has been solved. It was caused by my other codes.
