NextJS отправка на Build

не могу запустить buid приложения. есть:

export const getStaticPaths = async () => {
    const urlBed:string = process.env.DOMAIN_NAME+'/api/get-bedding';
    const res = await fetch(urlBed)
    const beddings: IBedding[] =await res.json()

    const paths = beddings.map((bedding: IBedding) => {
        return {
            // @ts-ignore
            params: { id: bedding.id.toString()}
        }
    })
    return {
        paths,
        fallback: false
    }
}

запускаю npm run build:

Build error occurred FetchError: request to http://127.0.0.1/api/get-bedding failed, reason: connect ECONNREFUSED 127.0.0.1:80 at ClientRequest. (E:\NodeJsProjects\terona\terona\node_modules\next\dist\compiled\node-fetch\index.js:1:64142) at ClientRequest.emit (node:events:527:28) at Socket.socketErrorListener (node:_http_client:454:9) at Socket.emit (node:events:527:28) at emitErrorNT (node:internal/streams/destroy:157:8) at emitErrorCloseNT (node:internal/streams/destroy:122:3) at processTicksAndRejections (node:internal/process/task_queues:83:21) { type: 'system', errno: 'ECONNREFUSED', code: 'ECONNREFUSED' }

Я понимаю что во время build приложение не запущено, но как поправить?
