❔ Extract PDF SDK logic inside .Net Blazor component not working, but does work with razor page

I'm making use of Adobe Extract PDF SDK in my .Net Blazor app. The SDK logic is inside a Blazor component. Credentials work. Directory pathways work. What doesn't work is the actual extraction. Strangely, when I converted the Blazor component to a razor page making use of OnGet and OnPost, the extraction worked. So this tells me there is something going on with Blazor, perhaps with Signal-R. But that's where I'm stuck.
