TypeError: Cannot read properties of undefined (reading 'startsWith')

Since v14.1.0 we have started seeing an error occurring at

hibp/src/api/fetch-polyfill.ts

Line 12 in b2901eb

process.versions.node.startsWith('18.')

.

Debugging through I can see that process is actually defined when this code executes. I think perhaps this could be a Next.js thing but I am not totally sure. We call hibp from the browser I should add.

I wonder if using typeof window === 'undefined' rather than typeof process !== 'undefined' might be an approach which would have the same effect but not impact on Next.js users.

Thanks.

Hmm, I tested this in a vanilla Vite app and a Remix app and it worked fine, so I agree this may be a Next.js specific issue. I'll try to reproduce it here in a bit. They probably do something weird to process - we might be able to hack around it with optional chaining.

We used the window check previously, but that is flawed as it prevents usage in web workers and extension background threads.

hibp v14.1.1 should resolve your issue @PodStuart. I confirmed the problem and this solution in fresh Pages Router and App Router projects. Sorry about the hassle and thanks for reporting it!
