[Error] Compilation Error When Importing Component

[snowons]

I'm encountering a compilation error while using your developed component. I've tried various solutions to fix the issue, but it still persists. Here are the specific details:
Failed to compile.

./node_modules/@j3lte/react-xml-view/build/index.esm.js 46:54
Module parse failed: Unexpected token (46:54)
File was processed with these loaders:

• ./node_modules/react-scripts/node_modules/babel-loader/lib/index.js
  You may need an additional loader to handle the result of these loaders.
  | charIndexToByteIndex() {
  | let e = arguments.length > 0 && arguments[0] !== undefined ? arguments[0] : this.charIndex;

return this.multiByteMode ? this.charsToBytes[e] ?? 1 / 0 : e;

| }
