      Hi,
      I’ve updated to the latest Version today using at first the update script. I have some trouble with the calendar display and the newsfeed. I just started a blank Mirror instance. A module #server_functions is missing. I don’t know how to fix that.

      What I’ve tried so far is

      • getting serverOnly folder from the repo manually
      • switched manually again to master branch and reinstalled all node_modules
      • uses npm install manually

      This is the log:

        what did you change in package.json?

        git diff package.json

            #server_functions is an alias for js/server_functions.js which is defined in package.json:

                    "imports": {
                            "#module_functions": {
                                    "default": "./js/module_functions.js"
                            },
                            "#server_functions": {
                                    "default": "./js/server_functions.js"
                            }
                    },
            

            Because axios is the only diff your package.json should contain above lines.

            I have no idea anymore (maybe corrupt sd card).

                  @sdetweil and @karsten13, I think I solved my problem.
                  In the beginning when I used the update script it stopped with the node-version but didn’t update. So I updated manually by using the original code from Node JS. So I installed node v22.20.0. Later I went again down to v22.18.0. Maybe this caused some trouble. But Maybe not. rm -rf node_modules and npm install I did already 3 times before.

                  But now I modified the calendarfetcher.js and newsfeedfetcher.js:

                  This was removed:

                  const { getUserAgent } = require("#server_functions");
                  const { scheduleTimer } = require("#module_functions");
                  
                  

                  and replaced by this:

                  const getUserAgent = () => "MagicMirror v2.33.0";
                  const scheduleTimer = (timerRef, interval, callback) => {
                      clearTimeout(timerRef);
                      return setTimeout(callback, interval);
                  };
                  

                  No errors and Calendar/Newsfeed is displayed as before. I don’t know exactly if there are any new issues now but so far I’m happy.

                  Regards, Chris.
