Hi,
I am using the appleDeviceSpecsForLaunchImages in my Next.js application to dynamically create splash screen images for the different screen sizes. This works perfectly fine in local dev and prod builds.

Building the application on Vercel works as well, but when I launch the application I get the following 500 error:

Error: ENOENT: no such file or directory, open '/vercel/path0/node_modules/pwa-asset-generator/dist/config/apple-fallback-data.json'

I use this import statement:

import { appleDeviceSpecsForLaunchImages } from 'pwa-asset-generator'

It worked with version 7 of pwa-asset-generator, so I guess it is related to switching to ESM.

I found a workaround though, by directly importing the JSON file with the following import:

import appleDeviceSpecsForLaunchImages from 'pwa-asset-generator/dist/config/apple-fallback-data.json' with { type: 'json' } 

The type assertion using with is crucial here.

System (please complete the following information):

• node version 22.14
• npm version 10.9.2
• pwa-asset-generator version 8.0.4
