Ist es sicher, diese Webpack-Warnung zu ignorieren?

Ich habe eine seltsame Warnung im Webpack gefunden. Beim Parsen von process.env mit babel-loader. In TypeError: result.setExpression is not a function ist eine Warnung (webpack/lib/Parser.js) aufgetreten. Ich bin in einem großen Projekt und möchte, dass mein Kern super solide ist. Ist es also sicher, diese Warnung zu ignorieren, da Webpack sie explizit abfängt und "Fehler ignorieren" kommentiert?

Die Warnung (TypeError: result.setExpression is not a function) ist hier aufgetreten (webpack/lib/Parser.js https://github.com/webpack/webpack/blob/2361995a429794d372d61e3fb628dea3929e0ca4/lib/Parser.js#L1987 ).

evaluateExpression(expression) {
    try {
        const hook = this.hooks.evaluate.get(expression.type);
        if (hook !== undefined) {
            const result = hook.call(expression);
            if (result !== undefined) {
                if (result) {
                    result.setExpression(expression);
                }
                return result;
            }
        }
    } catch (e) {
        console.warn(e);
        // ignore error
    }
    return new BasicEvaluatedExpression()
        .setRange(expression.range)
        .setExpression(expression);
}

Ich habe diese result gedruckt und festgestellt, dass es so ist

BasicEvaluatedExpression {
  type: 0,
  range: [ 945, 956 ],
  falsy: false,
  truthy: true,
  bool: null,
  number: null,
  regExp: null,
  string: null,
  quasis: null,
  array: null,
  items: null,
  options: null,
  prefix: null,
  postfix: null } 

Ich habe auch die expression gedruckt

{
  type: 'MemberExpression',
  start: 945,
  end: 956,
  loc: 
   SourceLocation {
     start: Position { line: 16, column: 13 },
     end: Position { line: 16, column: 24 } },
  range: [ 945, 956 ],
  object: 
   Node {
     type: 'Identifier',
     start: 945,
     end: 952,
     loc: SourceLocation { start: [Object], end: [Object] },
     range: [ 945, 952 ],
     name: 'process' },
  property: 
   Node {
     type: 'Identifier',
     start: 953,
     end: 956,
     loc: SourceLocation { start: [Object], end: [Object] },
     range: [ 953, 956 ],
     name: 'env' },
  computed: false }

Der process.env kam von so etwas wie var isProd = process.env && process.env.NODE_ENV === 'production';
