Knowledge Object Explorer: no tree!

[gabriel_vasseur]

I have just installed the Knowledge Object Explorer app (apparently I have not enough karma to post links but you'll see it on SplunkBase) and it doesn't work for me. It doesn't show any tree.

If I type anything (say "tag=authentication") in the search box, choosing any app (say "Enterprise Security"), I can see something happening in the normalizedSearch text area (could be a huge string depending on the search) but I can't see the tree, just a big empty gray area where the tree should be. I haven't checked the "skip tree" box either.

All the tabs on the bottom right ("Field Aliases", "Calculated Fields", "Reverse Lookups", "Event Types", "Tags" and "Macros") are empty too.

This is on Splunk 6.4.0.

Yeah, I'm using the native JS Promise API to easily implement asynchronous caches - that way, I only ask Splunk's REST API for the field aliases of a particular field once and then reuse the results. You can observe that happening when the counter in the progress bar accelerates its increments significantly.

The Promise API is supported since about FF 29, Splunk 6.2 requires at least FF ESR 31.2 while 6.3+ require latest... so yeah, update your browser.

What browser are you using?
Depending on the browser, there's a web console, debugger, etc. that should show Javascript errors. Do open that and post any errors you see.

I am using an old version of firefox (don't ask). I can see a bunch of CSS errors when loading the app and a single JS error when launching the request: "ReferenceError: Promise is not defined". I'm guessing updating the browser will solve the issue?
