Web AppBuilder Developer Edition - Can't create new Apps

KieranO_Donnell2 — Tue, 06 Oct 2015 20:56:15 GMT

Hi all,

I've been using Web AppBuilder Developer Edition (1.2) since its release and have just run into a new error

I am unable to create any new Apps, as a blank box (like an error message would) appears with only the option to click Ok.
See screenshot below.

I have made a number of new apps with this latest Developer Edition of Web AppBuilder, and am still able to edit the existing apps.
This issue has only recently sprung up, and is seemingly random as nothing should have changed to create the problem.

Has anyone else experienced this problem?

Cheers,
Kieran

Kieran,

Can you check your browsers web console and tell us what error details are listed there?

Kieran/Alba - how many is "a number of new apps"? Maybe they is a limit in WAB? (one I haven't hit yet). I'm more curious about right now myself. Or maybe a practical or physical limit of the machine?

A workaround might be to create a new instance of WAB (i.e., unzip the WAB download to a new folder and start a new version). Then "download" one of you developed apps and import it into the new version as a starting point (if it's the same version, you should be able to copy the folder over instead I think). The problem of course with that is I think you will have to move all your custom widgets over again for any new apps (or copy over the folders in the <WAB>\client\stemapp folders. I haven't tried this, but that is what I would try.

I had this same problem! I also couldn't duplicate an existing app.

I ended up doing what Rebecca suggested: downloaded all my map apps, archived the existing "arcgis-web-appbuilder-1.2" folder, re-installing, copied over the widgets from before, and then imported the zipped maps I was still working on.

It is a weird issue - for the first couple of days I had this problem, I could clear the cache, switch browsers, and/or restart the computer to get WAB back to running, but then all those options stopped working.

Hi Robert, I can't see any errors

Re: Web AppBuilder Developer Edition - Can't create new Apps

KieranO_Donnell2 — Sun, 11 Oct 2015 19:14:14 GMT

Thanks Rebecca,

It does not seem to be the number of apps, as I have tried deleting a few, but there's no change.

This workaround seems to have worked. The problem happens intermittently though so hopefully it does not return.

Cheers

It looks strange, could you post your server log, browser console log, browser network log? Thanks!

Any resolution to this? It's happening to me too.

I have both 1.1 and 1.2 installed, and they happily cohabitated since I installed 1.2 up until a short while ago, then 1.2 stopped letting me create new apps. 1.1 still works fine.

Using Chrome v46.0.2490.80m

When the empty message box is open, there is nothing except a XMLHttpRequest event deprecation notice.

Any ideas on this? I'm finding the problem reoccurring after making the new copy as Rebecca suggested, and that worked for a short while, but now it's happening again. Making new copies repeatedly isn't a good option long term, so if anyone has ideas, I'm all ears.

You may want to check out this thread and the workaround when trying to "save" an already created app. Not sure it there is any relation to the two issues....but maybe there is some connection as to why these things happen.

A much easier workaround is to simply Create a BASIC VIEWER.. it will run. Then you will be able to create DEFAULT again without issue.

MichaelRobb — Fri, 13 Nov 2015 09:10:47 GMT

Ive come across this, not sure what 'exactly' the problem is... however the easiest workaround I know is to create a new BASIC VIEWER app... then out of the list of copied items as seen in the cmd window (or appbuilder.logs) seems to replace the glitchy file...

Then you can create a DEFAULT Web App once again!

This could happen if Fiddler is running at the same time and your portal is running SSL

Kieran,

Delete signininfo.json file under ArcGIS-web-appbuilder-1.3/server. Exit and restart WAB

Re: Web AppBuilder Developer Edition - Can't create new Apps

NicholasBarger — Tue, 23 Feb 2016 12:55:39 GMT

I think Hunter might be into something. I've had this problem as well. My fixes have been to keep a copy with the LL widget already set up but no app in the list. When this happens I copy the clean version down and import the app back in to the WAB1.3. The last time I was also able to copy the entire client folder over from the broken WAB to the Working one and that also corrected the problem.

In my search for answers I looked into the //WAB/server/logs.appbuilder.log and found this error message...

[2016-02-22 10:55:36.175] [INFO] server - No token is found, redirect /webappbuilder to /webappbuilder?action=setportalurl

I also looked into the //WAB/server/db/apps file and at the end I was my test ones that failed and where they were being deleted. When it fails it seems to not completely write into this directory. One thing to note... my signininfo.json file appears to be correct.

Given the fact that I found the error message with the no token found I would say Hunter's response is likely correct. I just corrected this again yesterday before I found this thread. So, if it happens again I will try this solution.

I am having the same problem with WAB DE 2.0. I tried Hunter's solution, did not work. Looks like I will need to install a new version of the WAB with the Local Layer Widget and copy the Client Folder over to it. Thoughts?

JunshanLiu — Thu, 02 Jun 2016 02:29:59 GMT

I a known issue and we are still working on this. The reason is the generated app is is duplicated. The workaround is: if you have this error, click the OK button again and again until the app is created successfully.

Re: Web AppBuilder Developer Edition - Can't create new Apps

TimHayes1 — Thu, 02 Jun 2016 05:25:48 GMT

Junshan, you are a genius! I tried your solution and it worked. I adapted it to my situation:

I fixed the problem about the apps not duplicating or not being able to create a new app inside the WAB DE 2.0. For the app I wanted to copy, I just kept hitting Duplicate around 10-15 times. Eventually, the App duplicated. Also, this seemed to fix the error that prevented me from creating new apps. Very odd indeed. But the problem is now fixed and the WAB DE 2.0 runs like a brand new BMW.

I think Jack should give you a raise.

Junshan, here are two complete screenshots showing the WAB DE 2.0 Dos Box Window. I thought this could help in your debugging process.
