probably a good thing to do, moved from the doc thread

note that this could be tricky because the "error handler" would be thrown by the createViewState function so we could not really 'handle' this from the JBrowseReactLinearGenomeView component, since the user passes the return of createViewState to the component, so it would be 'outside of an ErrorHandler that we control'

might just be better to document the issue in storybook docs

didn't intend to close, but could probably close once storybook example is made and i ensure my above assessment is correct...

storybook example was added https://jbrowse.org/storybook/lgv/main/?path=/docs/error-handling--docs
