(node:65089) 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:65089) [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.

Reason:
- After upgrading the `Vue CLI` packages from v.4 to v.5 and trying to launch the application with `npm run serve` an error occurs in the terminal related to the `svg-symbol-sprite-loader` package.
Version 4.0.0 of `svg-symbol-sprite-loader` may not be compatible with `Vue CLI 5. There may be changes or incompatibilities in the way `Vue CLI 5` handles SVG loads and load modules.

Solution:
- Upgrade the `svg-symbol-sprite-loader` package from v.4 to v.5
