Question Help with modules_v4 issue

I have recently upgraded to webtrees version 2.1.0-alpha.1. I moved my custom reports to the modules_v4 folder and now I get the following response
"Unable to read file from location: volume1/web/ancestry.wersvdru.net/webtrees/modules_v4/Military-Report/resources/report.xml."

I checked on permissions and owner but these seem to be correct. I tried the example module report and I get the same thing.
github.com/webtrees/example-module-report/blob/main/module.php

php version - 7.4
Synology environment - DSM version 7

Thanks in advance.

This is a bug.

In some places, the resources folder is expected to be a full path (starting "/")

In others, it is expected to be relative to the root of the webtrees installation.

I will investigate...

This is fixed in the latest code.

Thank you very much.
