Last updated: Apr 10, 2021
Hello! I wonder if this is a known issue, I just upgraded an older project with
sanity upgrade
and now get
React is not defined
when I try to run it in the browser. The project really isn't complex but I can't seem to find the source of the problem.

Hi
user B
, could you check if there might be a missing React import in your schema definitions or custom components?
Alternatively, could you try removing your
node_modules
folder and
package-lock.json
+
yarn-lock.json
files before running
npm i
and trying once more to start the studio?

Thanks for the hint, I should have known better πŸ˜› - it was a missing import on a custom plugin.
