Desk Tool crashes with "Invalid path string" error when accessing post

Last updated: Nov 29, 2025

Hello everyone, I'm having an issue with the studio when trying to access one of the posts I have created."The ‘Desk’ tool crashed"
The studio functions perfectly otherwise, only having an issue with one particular post which I don't mind deleting.

Stack trace:

I was editing the schema and adding a custom image type in order to have a field for the alt text. I believe the issue begun after creating and adding that custom image type to the Post. Any suggestions on what I could possibly do?

AI Update

I can see you're experiencing an "Invalid path string" error in the Desk tool when trying to access a specific post. Based on the stack trace and your description, this is almost certainly related to the custom image type you added to your schema. The error is coming from ConnectorsOverlay which is part of the change tracking system in Sanity Studio, and the fromString function is failing to parse a path in your document.

Here are the steps to resolve this:

1. Delete the problematic document via API

Since you mentioned you don't mind deleting this post, the quickest solution is to delete it directly through the API or Vision tool:

Using Vision (in your Studio):

Go to the Vision tool in your Studio (usually at http://localhost:3333/vision)
Run this query to find your document:

*[_type == "post"] {_id, title}

Note the _id of the problematic post

Using the Management API:

You can use the Management API to delete the document. Get a token from manage.sanity.io with write permissions, then:

curl -X DELETE \
  'https://[YOUR-PROJECT-ID].api.sanity.io/v2021-06-07/data/mutate/[YOUR-DATASET]' \
  -H 'Authorization: Bearer [YOUR-TOKEN]' \
  -H 'Content-Type: application/json' \
  -d '{"mutations": [{"delete": {"id": "YOUR-DOCUMENT-ID"}}]}'

2. Fix your custom image schema

The root cause is likely in how you defined your custom image type. According to the Image Type documentation, make sure your custom image field follows this pattern:

{
  name: 'customImage',
  type: 'image',
  options: {
    hotspot: true
  },
  fields: [
    {
      name: 'alt',
      type: 'string',
      title: 'Alternative text',
    }
  ]
}

Common mistakes that cause path errors:

Adding nested objects incorrectly within the image type
Using reserved field names or invalid characters in field names
Improperly structured fields array
Missing or malformed _key values in array items

3. Clear your Studio's local cache

After fixing the schema:

# In your Studio directory
rm -rf node_modules/.cache
npm run dev

4. If you want to recover the document

If you need to save the content before deleting:

Export the document via Vision: *[_id == "YOUR-DOCUMENT-ID"][0]
Copy the output
Look for the image field and check if there's malformed data (empty strings, missing required properties, etc.)
Manually fix the data structure
Re-import it using a mutation after fixing your schema

The invalid path is likely in the image field's internal structure - possibly an empty or malformed _key value, an incorrectly nested field path, or a field name that doesn't match your schema definition.

Let me know if deleting the document and fixing your schema resolves the issue!
