linuxserver/grocy: "custom_js.html" not recognised

[mfkfx83]

Hello,

regarding the official documentation, there is a possibility to customise the html output by adding a file "custom_js.html" into the folder "/config/data/" (regarding the author of grocy, it is the folder where "grocy.db" is located. I created this file and put some snippets inside it (which are provided by the author on Reddit).
However, grocy does not recognise this file.

Startup log of the container:

Can someone please help me with that? For me it would be really important to get this "custom-init" working". Any help is much appreciated.

Thank you very much in advance!
