Media Node problem

Dashboard
1

I've a "media node" that, in his link (Animazione_Meteosat/meteo_animato.gif), point an animated GIF that is build every hour, but in dashboard the image never appear
Appear only when I deploy from the editor, stay visibile for some time (that I don't know how is), then disappear

If I point directly the link from any browser (http://XXX.XXX.XXX.XXX:1880/uimedia/Animazione_Meteosat/meteo_animato.gif), the animated GIF is always visible and updated

Anyone knows what kind of problem could be?

Thank you

Mario

well you haven't given much inormation to go on. You start off with:

But you don't give the name of the node or a like to the 'link' you are refering to.

You don't provide

  1. your flow
  2. what release of NR and node.js you are using (see your Node-RED start up log)
  3. what device and os you are running on
  4. if you are using Docker of Home automation

This information would go a long way to help people help you.

  • NR Version is 1.2.1 and run on a Raspberry PI with Debian Buster. I'm not using Docker

  • I have a bash script that generate an animated GIF that run every hour

  • In "media node" there is:

    immagine
    immagine708Ă—842 27.4 KB

    immagine
    immagine697Ă—841 104 KB

  • As you can see, in the "preview" I see tha animated GIF in action, but in Dashboard it appear only when I "DEPLOY", but after some time disappear

Thank you

So you still haven’t provided your flow
You haven’t given the name of the node (node-red-contrib-???????)
Why are you running such an old version of NR? The current version is v3.0.2

  1. flows.json (2.3 KB)

  2. node-red-contrib-ui-media

  3. For now I have no problem and all is OK. I'm scared when I do an update that something goes wrong. Is there a way in this case to roll back to previous version?

Thank you and sorry

There are many ways of backuping up your flow. Do a search using 'backup flow' and take a pick of one of the solutions.

In addition there is automatid backing up via GIT if you are using 'projects'. If you do a google search using 'node red projects tutorial' ou will even find some you-tube videos you can watch.

I backup the flow, but my concern is in case of update problems, to download all the node used and redo all the various configuration. I know I have to update it, but I have to find the right moment and have time to eventually redo everything.

If you look tru this thread Node red crash suddenly - #9 by 298christian you will fond a post bu @TotallyInformation showing his cron jobs to back up his flows

  • Ok. Thank you. I will look his job to learn something.

  • Instead, regarding my problem with "node-red-contrib-ui-media", do you have any news?

Thanks for all

I just imported your flow and I can't test anything since I don't have the script you are runing.

I would add a debug node (set to display the complete msg object) to each output of the exec node and see what you get.

I understand!!! :man_facepalming:

It is sufficient not to link the stdout output of the exec node with the input of the ui_media_node
In this way, animated GIF is always present...

I don't know why, but it works
