Error building app ionic capacitor in appflow

Question

When i building app ionic capacitor in appflow, i have this error. I updated packages through npm, I deleted the package-lock.json, updated the capacitor, the capacitor is in version 3, but still the error remains.

[18:58:02]: fastlane finished with errors

I received the same error as my projects capacitor.config was a TS file. To fix it I changed the capacitor.config.ts to a json file.

Initial Configuration File (capacitor.config.ts):

import { CapacitorConfig } from '@capacitor/cli';   

const config: CapacitorConfig = {   
  appId: 'com.blah.blahhh', 
  appName: 'blahh', 
  webDir: '../../dist/apps/blahh',  
  bundledWebRuntime: false, 
};  

export default config;

Updated Configuration File (capacitor.config.json):

{
  "appId": "com.blah.blahhh",
  "appName": "blahh",
  "webDir": "../../dist/apps/blahh",
  "bundledWebRuntime": false
}

By using the JSON format for the capacitor.config file, the issue was resolved, and the project could be built successfully on AppFlow.
