Dashboard template httpstatic (Node-red on NAS/Docker instance)

Dashboard
1

Dear all,

got a setup/understanding issue with my Node-red Docker based installation on my QNAP NAS . I would like to use the nice steel gauges from https://laptrinhx.com/steelseries-and-node-red-3482335268/ in my dashboard. They are loaded with the script template and need to have the httpstatic directory to be pointed at a location of choice where you need to put the two js files. Some also use this to store and load pictures I believe.

I do have changed the set the httpstatic line in the settings.js to : httpStatic: '/data/myjs', and copied the two files to the very same directory on my docker instance. Unfortunately I do have a empty Dashboard loaded that just displays the name of the template object with a wite frame :frowning:

Interestingly I do have created a 2nd simple flow that just creates a file and used the “current” directory to store a timestamp. When I looked in the console that new file was strangely created in the /usr/src/node-red directory. Well I copied the two java files to that directory too but with out success. The Dashboard is still empty.

Now as beginner I am stuck with ideas and would appreciate any help. Below my configuration :

The dashboard template has got the following code :
