Build of DICOM-Viewer in own Nextcloud Docker container fails

[PReichetanz]

Describe the bug
When trying to install the DICOM-Viewer in a docker container of Nextcloud, the described build steps fail due to an error with @ohif/app:build:viewer:nextcloud. It is possible to enable the Dicom-Viewer app (without downloading it, so the app itself is available), but .dcm-files are not opened, only downloaded.

To Reproduce
Steps to reproduce the behavior:

1. Set up a docker container for Nextcloud as described here, I used the compose.yml example described here.
2. Start container and enter shell with docker compose up -d and docker exec -it <containername> bash
3. Install git: apt-get -y update + apt-get -y install git
4. Install node@20 and npm via nvm as described in the homepage
5. Install yarn npm install yarn
6. Clone DICOM-Viewer app: cd apps, git clone https://github.com/ayselafsar/dicomviewer.git
7. Replace empty acanio-viewer folder with clone of the repo: rm -rf acanio-viewer, git clone https://github.com/acanio/acanio-viewer.git
8. Run build of DICOM-Viewer: npm run build (fails with exit code 1, see screenshots below)
9. Open Nextcloud on localhost:8080, login and enable the DICOM Viewer app.
10. Upload a .dcm-file and try to open it in browser.

Expected behavior
I can build the DICOM Viewer package, enable the DICOM-Viewer app in my Nextcloud and it displays .dcm files in the browser as intended.

Screenshots
Terminal output:

Trying to open a .dcm file after enabling the app shows this error message:
