Unable to build using Docker

Hi, i'm new to mumble-web and what i tested in your demo server is really impressive ! For a project I need to do some changes to the source-code, but I can't figure out how to build it. When building with the provided Dockerfile, this is what happens.

Step 8/15 : RUN cd /home/node && npm install && npm run build ---> Running in d1d3c34e16ca npm WARN old lockfile npm WARN old lockfile The package-lock.json file was created with an old version of npm, npm WARN old lockfile so supplemental metadata must be fetched from the registry. npm WARN old lockfile npm WARN old lockfile This is a one-time fix-up, please be patient... npm WARN old lockfile npm WARN EBADENGINE Unsupported engine { npm WARN EBADENGINE package: 'drop-stream@0.1.1', npm WARN EBADENGINE required: { node: '^0.11 || ^0.10' }, npm WARN EBADENGINE current: { node: 'v16.14.2', npm: '8.6.0' } npm WARN EBADENGINE } npm WARN EBADENGINE Unsupported engine { npm WARN EBADENGINE package: 'webrtc-adapter@2.1.0', npm WARN EBADENGINE required: { npm: '^3.10.0' }, npm WARN EBADENGINE current: { node: 'v16.14.2', npm: '8.6.0' } npm WARN EBADENGINE } npm WARN deprecated urix@0.1.0: Please see https://github.com/lydell/urix#deprecated npm WARN deprecated resolve-url@0.2.1: https://github.com/lydell/resolve-url#deprecated npm WARN deprecated source-map-resolve@0.5.3: See https://github.com/lydell/source-map-resolve#deprecated npm WARN deprecated source-map-url@0.4.0: See https://github.com/lydell/source-map-url#deprecated npm WARN deprecated ini@1.3.5: Please update to ini >=1.3.6 to avoid a prototype pollution issue npm WARN deprecated uuid@3.4.0: Please upgrade to version 7 or higher.

Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled.

I would be very grateful if you know how to help me with this issue.

Have a nice day !
