Encountering a Javascript error while trying to optimize bundling operations

After bundling my JavaScript with the .net setting

BundleTable.EnableOptimizations = true;
, I've encountered a peculiar issue.

Here's the snippet of the generated code causing the error (simplified):

var somVar = new b({
        searchUrl: "/someUrl",
        data: n => {
            query: n.term,
            page: n.page,
            teamId: this.props.teamId,
            season: this.props.season
        },
        resultFormat: this.formatState,
        resultSort: this.sortResults,
        onSelect: this.handlePlayerSelect
    });

But on line 5, it throws an Unexpected token : error. I'm puzzled about why that might be happening. The scripts work fine without optimizations.

The non-optimized version looks like this:

var someVar = new Select2({
        searchUrl: "/someUrl",
        data: (params) => {
            return {
                query: params.term,
                page: params.page,
                teamId: this.props.teamId,
                season: this.props.season
            };
        },
        resultFormat: this.formatState,
        resultSort: this.sortResults,
        onSelect: this.handlePlayerSelect
    })

This is the original TypeScript version:

new Select2({
    searchUrl: "/someUrl",
    data: (params: Select2QueryOptions) => {
        return {
            query: params.term,
            page: params.page,
            teamId: this.props.teamId,
            season: this.props.season
        }
    },
    resultFormat: this.formatState,
    resultSort: this.sortResults,
    onSelect: this.handlePlayerSelect
} as ISelect2Props)

This code is part of an array passed as a submodule to a base module, so there's no specific variable it's attached to here.

Answer №1

The reason behind the unexpected optimization failure remains a mystery, but it is essential to address this issue promptly.

let someVariable = new b({
    searchUrl: "/specificURL",
    data: input => {
        return {
            query: input.term,
            page: input.page,
            teamId: this.props.teamId,
            season: this.props.season
        };
    },
    resultFormat: this.formatState,
    resultSort: this.sortResults,
    onSelect: this.handlePlayerSelect
});

It's worth noting that I made a slight modification by explicitly returning the data in a different manner.
