Getting error setting up project for Next.js/codegen

After setting up a new project for nextjs/codegen, I’m receiving the following error upon initial build:

error - Conflicting paths returned from getStaticPaths, paths must be unique per page.
See more info here: <>

path: "/dashboard/home" from page: "/[...catchall]" conflicts with path: "/dashboard/home" 
path: "/dashboard/sales" from page: "/[...catchall]" conflicts with path: "/dashboard/sales" 
path: "/dashboard/inventory" from page: "/[...catchall]" conflicts with path: "/dashboard/inventory" 
path: "/dashboard/reports" from page: "/[...catchall]" conflicts with path: "/dashboard/reports" 
path: "/dashboard/dashboard" from page: "/[...catchall]" conflicts with path: "/dashboard/dashboard" 

Here’s my /pages/[[...catchall]].tsx

import * as React from 'react';
import {
} from '@plasmicapp/loader-nextjs';
import { GetStaticPaths, GetStaticProps } from 'next';
import Error from 'next/error';
import { useRouter } from 'next/router';
import { PLASMIC } from '../plasmic-init';

 * Use fetchPages() to fetch list of pages that have been created in Plasmic
export const getStaticPaths: GetStaticPaths = async () => {
    const pages = await PLASMIC.fetchPages();
    return {
        paths: => ({
            params: { catchall: page.path.substring(1).split('/') }
        fallback: 'blocking'

 * For each page, pre-fetch the data we need to render it
export const getStaticProps: GetStaticProps = async (context) => {
    const { catchall } = context.params ?? {};

    // Convert the catchall param into a path string
    const plasmicPath =
        typeof catchall === 'string' ? catchall : Array.isArray(catchall) ? `/${catchall.join('/')}` : '/';
    const plasmicData = await PLASMIC.maybeFetchComponentData(plasmicPath);
    if (!plasmicData) {
        // This is some non-Plasmic catch-all page
        return {
            props: {}

    // This is a path that Plasmic knows about.
    const pageMeta = plasmicData.entryCompMetas[0];

    // Cache the necessary data fetched for the page.
    const queryCache = await extractPlasmicQueryData(
        <PlasmicRootProvider loader={PLASMIC} prefetchedData={plasmicData} pageParams={pageMeta.params}>
            <PlasmicComponent component={pageMeta.displayName} />

    // Pass the data in as props.
    return {
        props: { plasmicData, queryCache },

        // Using incremental static regeneration, will invalidate this page
        // after 300s (no deploy webhooks needed)
        revalidate: 300

 * Actually render the page!
export default function CatchallPage(props: { plasmicData?: ComponentRenderData; queryCache?: Record<string, any> }) {
    const { plasmicData, queryCache } = props;
    const router = useRouter();
    if (!plasmicData || plasmicData.entryCompMetas.length === 0) {
        return <Error statusCode={404} />;
    const pageMeta = plasmicData.entryCompMetas[0];
    return (
        // Pass in the data fetched in getStaticProps as prefetchedData
                // pageMeta.displayName contains the name of the component you fetched.
            <PlasmicComponent component={pageMeta.displayName} />

Hey @parliamentary_trout can you dm me your proejct ID?

Hey, I’m also getting the same error message (but not in codegen) - could I get some advice?
path: "/class" from page: "/[[...catchall]]" conflicts with path: "/class"

this can happen if you also have other pages in your nextjs project with the /class path

I found that I can’t use a [[...catchall]] in my project because after publishing in Plasmic Studio, the plasmicops bot automatically adds a page.tsx file back for each page
