(node:19636) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'trim' of undefined

Description When trying to build the project I'm getting this: (node:19636) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'trim' of undefined at …\node_modules\svg-spritemap-webpack-plugin\lib\generate-svg.js:161:26

Expected behavior To build normally, probably with warning about broken SVG-file

Actual behavior Build freezes on the error: (node:19636) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag--unhandled-rejections=strict(see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1) (node:19636) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
