It was rather trivial to add the error message, here is how: in uglify-js module, added a error reporting log to the file lib\parse.js in following method: function js_error(message, filename, line, col, pos) { console.log(message, filename, line, col, pos); throw new JS_Parse_Error(message, filename, line, col, pos); }; Looks like the error handling of fault barrier doesn't do what it supposed to. @PitaJ Thank again for your help.

I work on nodebb 1.5.3 and accidentally made the grave mistake of installing a plugin using ACP and ended up losing all my development repos of non 'npm'ed plugins. At that point I decided to upgrade to latest 1.7.3 release since a fix (#6032) for this issue was supposed to be committed into that build. While I checked breaking change lists for 1.6.0 and 1.7.0, apparently I have over looked something since my list/grid topic-list show up all messed up (with no errors in console). I have a bootstrap based listview and gridview of the topics and I use JS code to select between them but now my page layout is gone like one of the libraries is not loading but I am not sure which one since I don't use anything other than jquery and bootstrap.I cannot figure this out but suspect it may be issue (#5980.) Any help would be appreciated and thank you in advance. Edit: I get the following error intermittently after several clicks and I am hoping to be related: Parsing failed for template D:\NodeBB-1.7.3\build\public\templates\category.js: Error: Parsing failed for template D:\NodeBB-1.7.3\build\public\templates\category.js: Script execution timed out. at ContextifyScript.Script.runInContext (vm.js:53:29) at ContextifyScript.Script.runInNewContext (vm.js:59:15) at Object.runInNewContext (vm.js:112:38) at evaluate (D:\NodeBB-1.7.3\node_modules\benchpressjs\build\lib\evaluate.js:17:6) at fs.readFile (D:\NodeBB-1.7.3\node_modules\benchpressjs\build\lib\express.js:39:53) at D:\NodeBB-1.7.3\node_modules\graceful-fs\graceful-fs.js:78:16 at tryToString (fs.js:513:3) at FSReqWrap.readFileAfterClose [as oncomplete] (fs.js:501:12) Parsing failed for template D:\NodeBB-1.7.3\build\public\templates\500.js: Error: Parsing failed for template D:\NodeBB-1.7.3\build\public\templates\500.js: Script execution timed out. at ContextifyScript.Script.runInContext (vm.js:53:29) at ContextifyScript.Script.runInNewContext (vm.js:59:15) at Object.runInNewContext (vm.js:112:38) at evaluate (D:\NodeBB-1.7.3\node_modules\benchpressjs\build\lib\evaluate.js:17:6) at fs.readFile (D:\NodeBB-1.7.3\node_modules\benchpressjs\build\lib\express.js:39:53) at D:\NodeBB-1.7.3\node_modules\graceful-fs\graceful-fs.js:78:16 at tryToString (fs.js:513:3) at FSReqWrap.readFileAfterClose [as oncomplete] (fs.js:501:12) 2017-12-31T06:55:43.950Z [1840] -

@esfandiar Downgraded the node version and it seems that the issue is now resolved. Thanks.
