Stack Trace: TypeError: Cannot Read Properties of Undefined (Reading 'Name')

10 replies
Last updated: Apr 14, 2022
I've inherited a project and running into an issue when attempting to create a new document. I get the following error message: 
TypeError: Cannot read properties of undefined (reading 'name')
. This is only happening when creating a new document of this type, but not when opening existing documents. I've even commented out most of the fields except for title & slug, and the issue is persistent

Hi Julia!
This is the structure builder for it:


export const ProductsMenuItem = S.listItem()
  .title("Products")
  .icon(BsTag)
  .child(
    S.list()
      .title("Products")
      .items([
        S.listItem()
          .title("Products")
          .schemaType("product")
          .child(
            S.documentTypeList("product")
              .title("Products")
              .child((documentId) =>
                S.document()
                  .documentId(documentId)
                  .views([
                    S.view.form().icon(FiEdit),
                    S.view
                      .component(IframePreview)
                      .options({ previewURL })
                      .title("Web Preview")
                      .icon(BsEye),
                  ])
              )
          )
          .icon(BsTag),
        S.listItem()
          .title("Collections")
          .schemaType("collection")
          .child(
            S.documentTypeList("collection")
              .title("Collections")
              .child((documentId) => S.document().documentId(documentId))
          )
          .icon(BsGrid),
        S.listItem()
          .title("Categories")
          .schemaType("category")
          .child(
            S.documentTypeList("category")
              .title("Categories")
              .child((documentId) => S.document().documentId(documentId))
          )
          .icon(BsCardList),
        S.listItem()
          .title("Shared Product Copy")
          .schemaType("productCopy")
          .child(
            S.documentTypeList("productCopy")
              .title("Shared Product Copy")
              .child((documentId) => S.document().documentId(documentId))
          )
          .icon(BsCollection),
      ])
  );
and this is the schema:


export default {
  name: "collection",
  title: "Product Collection",
  type: "document",
  fields: [
    {
      name: "title",
      title: "Title",
      type: "string",
    },
    {
      name: "slug",
      title: "Slug",
      type: "slug",
      options: {
        source: "content.main.title",
        maxLength: 96,
      },
      validation: (Rule) => Rule.required(),
    },
    {
      name: "illustration",
      title: "Illustration",
      type: "figure",
    },
    {
      name: "madeIn",
      title: "Made in ...",
      type: "string",
    },
    {
      name: "description",
      title: "Description",
      type: "text",
      rows: 3,
    },
    {
      name: "products",
      title: "Products",
      type: "array",
      of: [
        {
          type: "reference",
          to: [{ type: "product" }],
        },
      ],
    },
  ],
  preview: {
    select: {
      title: "title",
      media: "illustration",
    },
  },
};

hmm ok, I removed your custom types and refs. The schema seems ok.

export default {
  name: "collection",
  title: "Product Collection",
  type: "document",
  fields: [
    {
      name: "title",
      title: "Title",
      type: "string",
    },
    {
      name: "slug",
      title: "Slug",
      type: "slug",
      options: {
        // source: "content.main.title",
        source: "title",
        maxLength: 96,
      },
      validation: (Rule) => Rule.required(),
    },
    // {
    //   name: "illustration",
    //   title: "Illustration",
    //   type: "figure",
    // },
    {
      name: "madeIn",
      title: "Made in ...",
      type: "string",
    },
    {
      name: "description",
      title: "Description",
      type: "text",
      rows: 3,
    },
  //   {
  //     name: "products",
  //     title: "Products",
  //     type: "array",
  //     of: [
  //       {
  //         type: "reference",
  //         to: [{ type: "product" }],
  //       },
  //     ],
  //   },
  ],
  // preview: {
  //   select: {
  //     title: "title",
  //     media: "illustration",
  //   },
  // },
}

Hmmm, I commented everything out except for the title &amp; slug and still ran into the issue... I'll keep checking
Apr 13, 2022, 8:14 PM
user U
yeah... same issue 🤔
Apr 13, 2022, 8:17 PM
I still feel like a noob with structure builder. Good practice op!
this
should just list document titles for collection type docs under the parent…
S.listItem()
          .title("Collections")
          .schemaType("collection")
          .child(
            S.documentTypeList("collection")
              .title("Collections")
              .child((documentId) => S.document().documentId(documentId))
          )
          .icon(BsGrid),
I may suggest trying to isolate what part of the
structure builder is causing issues. Try removing the structure builder in a test branch. This should just render each doc type and then you can make sure that your references and custom objects/types all work as intended. Maybe someone else can see something in your structure -vs- schema that I’m not. I’m building something kinda similar too and will circle back if any 💡 go off.
remove the builder part from 
./sanity.json
to test similar to this:
"parts": [
    {
      "name": "part:@sanity/base/schema",
      "path": "./schemas/schema.js"
    },
    // - {
    // -   "name": "part:@sanity/desk-tool/structure",
    // -   "path": "./deskStructure.js"
    // - }
  ]

Looks like a pretty complex structure too… I’d definitely try isolating that at a very high level first with your full typical schema. And if the error still happens with structure builder removed - you’d be certain it’s an issue with referenced documents or objects.
Apr 13, 2022, 8:22 PM
it may also be good to check if custom document actions are being used - this could be another break point that can cause a relatively generic error like this
Apr 13, 2022, 8:24 PM
along with all this, don’t forget typical node troubleshooting - deleting modules, possibly also deleting the lock file - rebuilding

thanks for the note on the structure. I inherited this project and it seems some of the syntax might have been out of date. Refactored and all is back to normal! Thanks
Apr 14, 2022, 3:33 PM
omg awesome, I feel your pain with inheriting a thing. Maybe you can find some joy in making it better. It’s a genuinely fun platform.
