I am generating static params for my pages but I always get error from different page numbers (in the screenshot, it is
/list/characters/26, so the page number giving error is 26, but it always changes in every build). Is there a way to handle errors in generateStaticParams()?2 Replies

export async function generateStaticParams() {
// Getting discoverData used for main page, then getting display data from getDisplayData, to fetch entities list data in the following function (allPagesData).
const entityDisplayDataArray = discoverData.map((item) =>
getDisplayData(item.search as EntityType)
);
// Fetching every entity type's page 1 data.
const allPagesData = await Promise.all(
entityDisplayDataArray.map(async (item) => getListPage(item!.fetchKeyword, "1"))
);
// Looping over every entity's page data, and getting the total counts of each entity type.
const totalEntities = allPagesData.map(
(item, idx) => item[entityDisplayDataArray[idx]!.totalKeyword]
);
// Getting page counts for each entity
const totalPages = totalEntities.map((item) => Math.ceil(item / pageSize));
function getStaticParams() {
let staticParams = [];
for (let et = 0; et < discoverData.length; et++) {
const entityType = discoverData[et].search;
for (let pn = 1; pn <= totalPages[et]; pn++) {
staticParams.push({ entityType: entityType, pageNumber: pn.toString() });
}
}
return staticParams;
}
return getStaticParams();

Building the project locally doesn't thow any errors, but building it on Vercel does.
