Google Search Console – Article Schema Error with "Name" and "Publisher

I am using the OceanWp WordPress theme and I have activated the scheme option from the theme panel. When I checked the structure data via a structured data tool, the whole diagram works correctly but the diagram of the article gives these errors (in the screenshot below). I am using the free version of the theme and there is no support for me. I have no knowledge about coding, etc., but help me solve the problem.

Here is the screenshot.
