This is an open source code from the Github. I'm working on this Next.js project that uses Sanity as a CMS. However, I'm encountering an error related to the configuration of the Sanity client. Here is the error message I'm seeing in my terminal: Because I just need to create a env file and get the key. Then this will run correctly. javascript Error: Write token not found at eval (sanity\lib\write-client.ts:15:8)

What I Have Done: I created a Write Token in the Sanity dashboard and added it to my .env file:

makefile SANITY_WRITE_TOKEN=your_generated_token enter image description here And I tried several options here. It is not working.

• next.js
• environment-variables
• content-management-system
• sanity

• "enter image description here" is not a good description of an image. You should edit your question and describe, in words, what information you hope the image will give the reader. – Wyck Commented Nov 18, 2024 at 13:37

Adding the following code to next.config.ts worked for me:

module.exports = {
  env: {
    SANITY_API_WRITE_TOKEN: process.env.SANITY_API_WRITE_TOKEN,
  },
}

Next doesn't expose environment variables to the client by default. If your code is running in the client-side browser, you need to explicitly expose it in next.config.ts.
