I tried it like this:

Mutation: {
    createPost: (parent, args) => {
      return prisma.content.create({ 
        postinput: {
            name: args.name,
            content: args.content
          
        }
        
      })
    }
  }

But it is not working and giving me the following error: Unknown arg

postinput

in postinput for type Content. Did you mean

select

?\nArgument data is missing.
