I was in webpack Version 5.40.0

In one of my script, i use computed variable name to make promise with async/await /import.. in a stimulus controller

It was working fine. Today when i update my dependency and add webpack to last version : 5.52.1, the build fail with an error on the first [ in this line : this.['module' + datagridshortName[i]]

'Syntax Error: Unexpected token' on the bracket.

So how to use computed name variable in webpack encore now ??

I just got back to webpack 5.40 and the code work.

Thanks for your explanations / help :)

My code :

    async createDatagridSource(){
   
    let datagridScName = [];
    let datagridshortName = [];
    Object.entries(this.datagrid).forEach(entry => {
        const [key, value] = entry;
        datagridScName.push(value.controllerNameSc);
        datagridshortName.push(value.shortName);
    });

    for (let i = 0; i < datagridshortName.length; i++) {
        this.['module' + datagridshortName[i]] = await import('../js/datagrid_config/' + datagridScName[i] + '_config');
        this.module=this.['module' + datagridshortName[i]];
        this.datafields=this.module.datafields();

        this.columns=this.module.columns();
        this.columngroups=this.module.columngroups();
        this.config=this.module.config();

        //source des données initiales
        this.['source' + datagridshortName[i]] ={
            datafields:this.datafields,
            data: { "viewArchives" : this.viewArchives,...this.sourceOtherdata(datagridshortName[i])},
            url: this.datagrid[datagridshortName[i]].urlInit,

            //********************************
            id: 'data',
            type: "POST",
            datatype: "json",
            root: 'data',
        }
        //adaptater de la source
        this.['dataAdapter' + datagridshortName[i]] = new $.jqx.dataAdapter(this.['source' + datagridshortName[i]]);
    }

    //renvoi l'identifiant du premier datagrid
    return datagridshortName[0];
}
