WebpackError: Configuration must contain `projectId`

Hey everyone, I’ve noticed this has come up a few times before but there doesn’t seem to be a clear solution. Currently we are using the sanity client to fetch data for our Gatsby app. This is our configuration:

const client = require("@sanity/client");

export const sanityClient = client({
  projectId: process.env.SANITY_PROJECT_ID,
  dataset: process.env.SANITY_NODE_ENV,
  useCdn: false,
Everything ran fine during development, but we ran in some issues when trying to build. This is what we are getting:

  49 |
  50 |   if (projectBased && !newConfig.projectId) {
> 51 |     throw new Error('Configuration must contain `projectId`');
     | ^
  52 |   }
  53 |
  54 |   var isBrowser = typeof window !== 'undefined' && window.location && window.location.hostname;

  WebpackError: Configuration must contain `projectId`

  - config.js:51

  - sanityClient.js:78
Any help with this would be great appreciated. Thanks!

Hey ! This might me a problem coming from your .env not being properly loaded during build-time.
Maybe you can try to replace your
by a string and try to build again to see if it works.

Hi Hervé,Thank you for your reply! Strangely enough when we tried this earlier it didn’t work, but now it does!
Cheers for your help!
