 #### `ignoreErrors: boolean` **(default: `false`)**
 Set to `true` to bypass adding upload errors to the webpack compilation. Do this if you do not want to fail the build when sourcemap uploads fail. If you do not want to fail the build but you do want to see the failures as warnings, make sure `silent` option is set to `false`.

 ## App Configuration

 - See the [Rollbar source map](https://rollbar.com/docs/source-maps/) documentation
