Module build failed (from ./node_modules/handlebars-loader/index.js):

Nextcloud version (eg, 20.0.5): 24.0.0 dev (I see this in version.php, the value of OC_VersionString variable)
Operating system and version (eg, Ubuntu 20.04): Ubuntu 20.04
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.41
PHP version (eg, 7.4): 8.0.17

The issue you are facing:

As said here, I’m trying to run this command:

make build-js

But I get the following error in the terminal:

ERROR in ./core/src/OC/contactsmenu/list.handlebars

webpack 5.70.0 compiled with 1 error and 1 warning in 51616 ms
make: *** [Makefile:14: build-js] Error 1

I tried running make command both in docker host and docker container but got the same error.

After running this command, I now see that does not load.

Is this the first time you’ve seen this error? Yes

Steps to replicate it:

  1. cd /home/projects/files
  2. make build-js

The output of your Nextcloud log in Admin > Logging:

The URL does not load to have any output in web.

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

$CONFIG = array (

The output of your Apache/nginx/system log in /var/log/____:

There are no logs in error.log

Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.

There are no logs after I did activated log section in config.php.

It’s solved.
