Error when running npx changeset: "Cannot read properties of undefined (reading 'packageJson')"

Hello,

I'm encountering an issue when using Changesets in one of my projects. When running the npx changeset command, I receive the following error:

🦋  error TypeError: Cannot read properties of undefined (reading 'packageJson')
🦋  error     at createChangeset (/Users/agil/dev/demos/changelogs/pkg-changesets/node_modules/.pnpm/@changesets+cli@2.26.0/node_modules/@changesets/cli/dist/cli.cjs.dev.js:419:75)
🦋  error     at add (/Users/agil/dev/demos/changelogs/pkg-changesets/node_modules/.pnpm/@changesets+cli@2.26.0/node_modules/@changesets/cli/dist/cli.cjs.dev.js:533:26)
🦋  error     at async run$2 (/Users/agil/dev/demos/changelogs/pkg-changesets/node_modules/.pnpm/@changesets+cli@2.26.0/node_modules/@changesets/cli/dist/cli.cjs.dev.js:1330:5)
 ELIFECYCLE  Command failed with exit code 1.

I checked the project setup, and the package.json file is in the project root with the "name" property adequately defined. I have also tried removing the node_modules folder and pnpm-lock.yaml file, reinstalling the dependencies, and clearing the pnpm cache, but the error persists.

Interestingly, I have another project with a similar configuration where Changesets works without issues. You can find the problematic repository here: https://github.com/antoniogiroz/pkg-changesets/

I appreciate any help you can provide.

Ok, the error was caused by the missing "version" key in the package.json file.
