error when opening the "applications" menu on non-bl openbox install

hello : )
i installed openbox on a debian 9 and get an error when accessing the "application" menu ;
it reads as follow : "invalid output from pipe-menu "usr/bin/obamenu""
(the "debian" and others menus work)
it seems it might be this: Bug#887122: openbox: "Invalide output from pipe-menu "/usr/bin/obamenu"" but there are no answers there
anyone willing to guide a newb through this ?
thank you for reading : )
edit:title oops
editii:adding obamenu if it helps:

Re: error when opening the "applications" menu on non-bl openbox install

Did you follow the steps here under II? Or is there maybe a hint in that description that could help to figure out the culprit? It's not that complicated to install obamenu, just be careful at every step.

Re: error when opening the "applications" menu on non-bl openbox install

I have used obmenu and ctrl+p to add new pipemenu (before that I said: chmod +x obamenu) and this happened
https://cdn.scrot.moe/images/2018/02/09/oba.png
p.s. It looks like it is working (or at least it is outputing something xml-ish that doesn't break the menu).

^I think that looks good. In the tuto mentioned above there is also a short explanation for missing icons.

Re: error when opening the "applications" menu on non-bl openbox install

I haven't tried for long anymore so that the problem still persists for me : /
The tutorial is very clearly written, thank you, but not concise since the matter is quite complicated for newbs : (
I hope you magicians will one day find a way to simplify the process of getting dynamic menus : )

Re: error when opening the "applications" menu on non-bl openbox install

You could test the xml validity of what obamenu displays, from cli

path/to/obamenu > test.xml

will generate file test.xml, which you can copy/paste to some xml validator, like https://www.xmlvalidation.com/ . Then you will have some more info/idea on what's going on.
