Warning - The pageCount prop value provided is not an integer

[Indranil-R]

I am using NextJs to create an application. react-paginate throws warning.

(react-paginate): The pageCount prop value provided is not an integer (true). Did you forget a Math.ceil()?

I have tried with
const pageCount = (Math.ceil(table?.getPageCount() - 1));
const pageCount = parseInt(Math.ceil(table?.getPageCount() - 1));

console output is
console.log(pageCount)
number

Still its showing warning.

@Indranil-R please assign this one to me

[mdinjamul]

use like this

 const pageCosunt = parseInt(Math.ceil(table?.getPageCount() - 1) || 1);

just use a logical OR and add 1 by default.

Nope, this doesn't help.

same issue

[stanislavlyu]

only happens with production build, locally everything working properly. I checked that pageCount is number, i tried put pageCount manually with mock number but result still the same

[cozynooks]

we have same issue.
Is it relevant that Next.js is version 13.5?

[esotericbug]

Was having the same issue. Going back to Next.js version 13.5.3 seems to fix this issue in production builds.

[andreyfarias]

Same issue using Next.js v13.5.4. This error only occurs when building the application. In development, it works just fine.

Even when assigning a hard-coded value to pageCount, it still reads (undefined).

Currently, I have downgraded Next.js from v13.5.4 to v13.5.1 to make it work.

Seems like we are all having the issue #501

13.5.3 is working fine on a build, so it is something that happened specifically between 13.5.3 and 13.5.4.

Tracking it down further, it happened between 13.5.4-canary.8 (works) and 13.5.4-canary.9 (broken).

Any fix for this? Has anyone tested in Next.js 14?
