Some help in getting this up and running about tcc_apis HOT 8 OPEN

Hi Colum,

Thanks for reaching out.
I’ll have to look through all of this and give you answers. I don’t really have much free time over the next few business days, though, so it might be a week or so before I have some time to devote to it.

Thanks,
Kovner

Hi,
I made the user and server changes in the code, as per the readme. I created a 'rest' site (with id 'rest') and published the *.twbx file in the repo to this site.
The app runs up OK .. and allows me to sign in ...
However, after sign-in, it gives me an error msg "Could not locate unexpired trust ticket -1"
It appears to be using trusted/-1 as part of the API call .. and getting a 403 forbidden response ...
Only when I click on the "Analyze Your Own Data" ... and the app crashes (see console output at the bottom) ... do I see the Auth token and site id written to the console. Any idea what I might be going wrong here. It appears it is getting an auth token, but then not passing that properly to the REST call?

Also, I see further down in app.js, there are various references to C:\node\public\js and a csv_2_tde.py python script. I don't see any of this documented in the readme. Would you have some info around this, as ideally I would love to be able to refactor to get it working on linux ... as it looks like there's great material in here in terms of trying to get a better understanding for the API.

Is there anything in the code here that handles publishing the a workbook to the server via code? I don't think the REST API handles that ... but I was thinking maybe there was some other clever things being done to get around that.

Thanks,
Colum

No problem @Kovner ... whenever you find a chance. Much appreciated.

Sounds less like an app problem and more with the way Trusted
Authentication has been configured. Forget about the demo app for a moment

• are you sure that Trusted Tickets actually works? Try using this:

@russch . Thanks for the link. I ran through this set-up, however I still get a '-1' at the end. It points me to another KB article to resolve, but it appears this is blank, for some reason. http://kb.tableausoftware.com/articles/knowledgebase/common-issues-and-errors-associated-trusted-tickets

OK, so your problem isn't the app, it's the way Tableau Server is
configured.

At this point your best bet is to jump out to the Tableau User Forums on
tableausoftware.com. The folks on those boards can help you troubleshoot
your Tableau config so that trusted tickets works...then the app will work
too :)

p.js:27:9

Please can you help me .

Those look like deprecation warnings, not errors to me. It looks like it's running.

But this app is a few years old, Node and Express have advanced significantly since then, so there might be a lot of old or unworking code in there.

Hey
Thanks for reply,Ya that's not an error it just ban warning.But your code still working well. Thanks for sharing such a useful code.
