componentDidMount() {
   console.log(this.props.hours[0].openAt); 
   const date = new Date();
   const day = date.getDay();
   moment.locale('fr');
   for (let i = 0; i < this.props.hours.length; i++) {
       if (this.props.hours[i].day === day) {
           const format = 'hh:mm';
           const time = moment(date, format);
           const beforeTime = moment(this.props.hours[i].openAt, format);
            const afterTime = moment(this.props.hours[i].closeAt, format);

           if (time.isBetween(beforeTime, afterTime)) {
             this.setState({
                 ouvert: true
             });
           } else {
               this.setState({
                   ouvert: false
               });
           }

Got this error when upgrading from React Native 0.60 to 0.63 and using the latest version of Moment.js (2.29.4). Moment.js worked fine in all components except for the utils file (.fromNow() method particularly)

The error was caused by using moment.locale('fr', {}) for extending the French locale instead of moment.updateLocale('fr', {}).

After switching to updateLocale, the issue was resolved.

Solved it like this: (In my case i have english and italian localization to enable)

Imported my local localization files as:

import * as en from "./locale/en.json";
import * as it from "./locale/it.json";

Integrated moment localization

var moment = require("moment");
var itLocale = require("moment/locale/it");
var enLocale = require("moment/locale/en-gb");

moment.locale("en", enLocale);
moment.locale("it", itLocale);

Now works on debug/release mode.

I was facing this issue too and fixed it by downgrading the version of moment to 2.18.1.

If you're using moment-timezone then you would need to add the following in your package.json

"resolutions": {
    "moment-timezone/moment": "2.18.1"
  },
