Warning due to incomplete sourcemaps about fetch-event-source

[sureshHARDIYA]

I am also having same issue. Any solution would be appreciated.

There's a workaround.

If you are using webpack, set ignoreWarnings option to skip parse error. https://webpack.js.org/configuration/other-options/#ignorewarnings

module.exports = {
  // ...
  ignoreWarnings: [/Failed to parse source map/]
}

If you are using custome-cra, add the following code in config-overrides.js.

const addIgnoreWarnings = (_loaderOptions) => config => {
  // https://github.com/facebook/create-react-app/blob/0a827f69ab0d2ee3871ba9b71350031d8a81b7ae/packages/react-scripts/config/webpack.config.js#L353
  const loader = config.module.rules.find(({
    enforce, loader
  }) => enforce === 'pre' && typeof loader === 'string' && loader.includes('source-map-loader'));
  if (loader) {
    if (!config.ignoreWarnings) {
      config.ignoreWarnings = [];
    }
    config.ignoreWarnings.push(/Failed to parse source map/,)
  }
  return config
}


module.exports = {
  webpack: override(
    // ...
    addIgnoreWarnings(),
  )
};

@vishwam @firedog1024 Do you plan to maintain and accept PRs for this repo (e.g. #23)? Otherwise our team may just fork it if fixes won't be merged in.

Idem.

You might want to check out extended-eventsource as potential new replacement. It's codebase looks proper.

So, what's the solution here? Is this project abandoned I should use something else?
The problem obviously still exists…
