Help: cannot set custom yaml settings

[qdm12]

Hi there,

First of all, thanks for the nice program.

I made a Docker container version of it and a user reported a problem setting yaml settings on it.

Checking the browser console I have the following errors:

• When opening the settings dialog:

vue.runtime.esm.js:587 [Vue warn]: Error in mounted hook: "TypeError: Cannot read property 'rest' of undefined"

found in

Would you have any idea what I'm doing wrong? Is this a server side issue?

Thanks for you help!
