YunoHost Testing: error after the upgrade to 1.19.0~ynh1 version

[noccio]

The dashboard is not shown after the upgrade to 1.19.0~ynh1 and I have this error in nginx error log when I try to open the dashboard:

2023/01/08 22:11:37 [error] 102486#102486: *1 open() "/usr/share/nginx/html/ynhtheme/custom_portal.js" failed (2: No such file or directory), client: 62.19.94.242, server: cybervalley.noho.st, request: "GET /ynhtheme/custom_portal.js HTTP/2.0", host: "cybervalley.noho.st", referrer: "https://cybervalley.noho.st/dashboard"

Context

• Hardware: Qemu image
• YunoHost version: 11.1.2
• I have access to my server: Through SSH | through the webadmin
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no
  • Using, or trying to install package version/branch:
• If upgrading, current package version: can be found in the admin, or with yunohost app info $app_id

Hi! I don't know what it could be.

• Have you tried emptying cache?
• Can you please test the testing branch and see if some updates fixed it?

yunohost app upgrade uptime-kuma -u https://github.com/YunoHost-Apps/uptime-kuma_ynh/tree/testing --debug

• I changed also the browser, to be sure to have not any cache
• I tried also the testing branch

but the service continues to give me the same error.

P.S.: sorry for the delay for this answer.
