minify does not work ??

I'm compiling with minify.sh does not present an error but the application does not change.

/opt/traccar/tools# ./minify.sh
Sencha Cmd v6.5.3.6
[INF] Loading compiler context
[INF] Processing data with ClosureCompressor
[INF] JavaScript input level is NEXT and output level is ES5
[INF] Writing concatenated output to file /opt/traccar/web/app.min.js

It seems to work. Have you tried inspecting the output?

in the browser console gives these errors:

content.js: 4 Uncaught TypeError: Can not set property 'cssText' of undefined
     at content.js: 4

ext-all.js: 22 GET http: //.../api/session? _dc = 1524720097746 404 (Not Found).

I have erased possible caches, used other browsers.
In log of traccar: traccar-log-serve does not appear at all

By output I meant the JavaScript file.

I'm sorry but I do not know very well what you want to tell me, they are my first steps with Sencha and ExtJs, I do not know how to see the output of JavaScript.
I have placed -info in the minify.sh file and it shows:

But I think that this is not what you have indicated to me either.
How do I see the exit that you are indicating to me?

This is your output file:

/opt/traccar/web/app.min.js

I have directly executed /opt/traccar/web/app.min.js and I'm denied permission.
I have changed the permissions with 764 and I have run again and its response:

I have deleted app.min.js so that the compiler creates it again but I continue with the same error. The truth is that I do not know what to do I'm blocked

It the app working or not? It sounds like you still haven't checked the output.

If I use debug.htl it works with the changes, if I do not use debug.html it works but without the changes, it is as if it does not work in compiler, I am a bit lost without knowing what to do.

I created an html by loading the app.min.js and the answer is app.min.js: 1 Uncaught ReferenceError: Ext is not defined
