I don’t understand why it’s trying to go to this path

Error: ENOENT: no such file or directory, access’/home/pi/MagicMirror/js/…/modules/default/currentweather/node_helper.js’

sdetweil

@telmini because its looking for the (optional) node_helper.js of a module.
this one, currentweather doesnt use one

sdetweil

@telmini so the returncode is right but its not fatal in mm view.

It could probably be that the XmlHttpRequest is async and the page is already loaded when the request has finished executing.

Hi, I’m trying something similar. Have you managed to solve your issue using this fuction loadJSON? If not, did you find any solution to update config.js “dinamicaly”?

sdetweil

@tatianobusatto others have written js/python code that takes their settings ( file, database, web service) and applied to a model config.js. (all their modules with fake strings for keys, etc)
and call that js/python just before launching mm

in installers/mm.sh

tatianobusatto

@sdetweil thanks for the tip. Unfortunately, I couldn’t find a good js/python script example for that. For a while, I ended up creating a simple batch script to append multiple json config files for each module in between the config header and footer. In case you remember a place were I can find a thread for that discussion, please let me know.
