Last updated: Aug 11, 2021
Hi, After updating sanity to latest versions my schema (author) preview doesn't work anymore. the jobTitle comes back as undefined. Has anyone else encountered this problem after update?Here is my Authors.js code .

import { FiUser } from 'react-icons/fi'

import { createHeading, formatDate } from '../../helpers'

import SlugInput from 'sanity-plugin-better-slug'

import { isUniqueAcrossAllDocuments } from '../functions/isUniqueAcrossAllDocuments'

export default {
   name: 'author',
   title: 'Author',
   type: 'document',
   icon: FiUser,
   fields: [
      {
         name: 'name',
         title: 'Name',
         type: 'string'
      },
      {
         name: 'slug',
         title: 'Slug',
         type: 'slug',
         inputComponent: SlugInput,
         validation: (Rule) => Rule.required(),
         options: {
            source: 'name',
            maxLength: 100,
            basePath: '<http://localhost.com|localhost.com>',
            isUnique: isUniqueAcrossAllDocuments,
            slugify: (input) =&gt;
               input.toLowerCase().replace(/\s+/g, '-').slice(0, 100)
         }
      },
      {
         title: 'Job title',
         name: 'jobTitle',
         type: 'string',
         validation: (Rule) =&gt;
            Rule.required().error('This is required dear friend!'),
         options: {
            list: [
               // Others
               { title: 'Managing Partner', value: 'Managing Partner' },
               { title: 'Account Director', value: 'Account Director' },
               { title: 'Creative Director', value: 'Creative Director' },
               { title: 'Concepter', value: 'Concepter' },
               { title: 'Finance', value: 'Finance' },
               { title: 'Producer', value: 'Producer' },
               { title: 'Storyteller', value: 'Storyteller' },

               // Developers
               { title: 'Lead Developer', value: 'Lead Developer' },
               { title: 'Senior Developer', value: 'Senior Developer' },
               { title: 'Medior Developer', value: 'Medior Developer' },
               { title: 'Junior Developer', value: 'Junior Developer' },

               // Designers
               { title: 'Lead Designer', value: 'Lead Designer' },
               { title: 'Senior Designer', value: 'Senior Designer' },
               { title: 'Medior Designer', value: 'Medior Designer' },
               { title: 'Junior Designer', value: 'Junior Designer' },
               { title: 'Junior Creative', value: 'Junior Creative' }
            ]
         }
      },

      {
         name: 'bio',
         title: 'Bio',
         type: 'blockContent'
      },
      {
         name: 'authorImage',
         title: 'Author image',
         type: 'imageWithAltText'
      }
   ],

   preview: {
      select: {
         title: 'name',
         jobTitle: 'jobTitle',
         media: 'authorImage'
      },
      prepare(selection) {
         const { title, jobTitle } = selection

         return Object.assign({}, selection, {
            title: title,
            subtitle: jobTitle
         })
      }
   }
}

Hi,
user E
. I'm experiencing the exact same problem. I've been trying to isolate it and so far I've discovered the same issue in a clean sanity studio when you have a
string
field with a
list
option.
Jul 27, 2021, 8:29 AM
Here is my complete schema file that reproduces the problem. You can see that I'm setting a subtitle using
preview.select.subtitle
but when I set it to
pickSomething
it is blank.

// First, we must import the schema creator
import createSchema from 'part:@sanity/base/schema-creator'

// Then import schema types from any plugins that might expose them
import schemaTypes from 'all:part:@sanity/base/schema-type'

const obj = {
	title: "Obj",
	name: "obj",
	type: "object",
	fields: [
		{
			title: "Plain text",
			name: "plain",
			type: "string"
		},
		{
			title: "Pick something",
			name: "pickSomething",
			type: "string",
			options: {
				list: [
					{ title: "Alpha", value: "a" },
					{ title: "Bravo", value: "b" },
					{ title: "Charlie", value: "c" },
					{ title: "Delta", value: "d" },
					{ title: "Echo", value: "e" },
					{ title: "Foxtrot", value: "f" },
				]
			}
		}
	],
	preview: {
		select: {
			title: "plain",
			subtitle: "pickSomething"
		}
	}
}

const doc = {
	title: "Doc",
	name: "doc",
	type: "document",
	fields: [
		{
			title: "Pickers",
			name: "pickers",
			type: "array",
			of: [{ type: "obj" }]
		}
	]
}

// Then we give our schema to the builder and provide the result to Sanity
export default createSchema({
  // We name our schema
  name: 'default',
  // Then proceed to concatenate our document type
  // to the ones provided by any plugins that are installed
  types: schemaTypes.concat([
    /* Your types here! */
    obj,
    doc
  ]),
})

There seems to be an open issue for this bug already:

user A
