core: Unable to configure Solar edge integration

Problem

When configuring solarEdge integration I do not see any entities. I tried configuring through configuration and through integrations (and both). When I configure through configuration it shows up as “discovered” but it says I need to configure, when I try the dialog box does not close on submit, but instead returns focus to the first input field. No console or other logs are generated.
