ServiceNow IDE on PDI only halfway works

I installed IDE on my PDI several months ago but haven't had much time to play around.  It seemed to get stuck trying to scaffold the app.  It got stuck here and I waited hours.

Tonight I upgraded it to 2.1.1 and now it's worse.  Just opening IDE, I get two errors on the bottom right:

 

  • Cannot activate the 'Git Source Control' extension because it depends on an unknown 'servicenow.@servicenow/glider-extension-package-manager' extension.
  • Cannot activate the 'Fluent Build Service' extension because it depends on an unknown 'servicenow.@servicenow/glider-extension-package-manager' extension.

I also have the error below.  Incidentally, I use GitHub for several custom apps...so that error is only for IDE.   I installed it on one my company's non-prod instances.  Seems to work fine there.

Got any ideas why it won't work on my PDI?

 

Thanks

hey Roger! after the call we had with you today, we hopped into your instance and repaired the application and the IDE was loading fine after that. It looks like there might've been a hiccup in the upgrade engine (we're already showing logs to our upgrade team) in a previous repair attempt. This issue should not occur and we haven't had any other customer/user reporting upgrade issues. Please let us know if you encounter this again!

I noticed that, on my company's sandbox where I installed IDE, it's a different url than my PDI.

 

Company:  https://<company>.service-now.com/sn_glider_app/ide.do?sysparm_nostack=true 

PDI: https://dev202845.service-now.com/sn_glider_ide.do?sysparm_nostack=true  

 

I tried going to sn_glider_app on my PDI but get page not found.  Comparing versions, IDE is 2.1.1 on both instances. The Unified Developer Core is the same version on both instances.  The dependencies for that are the same.  The only difference that sticks out is the number of installed files. On my company instance, there are 275 versus 262 on my PDI. 

The only error in the installation log is:  Table 'sn_udc_experience_configuration' does not exist

That error exists on both instances.

Hi Roger, 

 

There was a migration to use the `sn_glider_app/ide.do` in the 2.0.4 release. VSCode is very noisy, many of the messages you see above do not affect the functionality. Have you tried doing operations in the IDE? You could try creating a workspace and then creating a Fluent app by launching the "Fluent: Create Fluent app".

I have 2.1.1 so why don't I have sn_glider_app/ide.do?

 

The problem is the I can't create workspaces or applications.  I don't even get the welcome screen:

When I launch ServiceNow IDE on my PDI, my screen looks like:

Creating or Browsing don't do anything.  There's a brief message in the start bar on the left that reads "Activating Extensions".  It goes away and nothing has changed.

@EdwinCoronado IDE works just fine on a new PDI.  It worked before and after I upgraded it to 2.1.1.

For anyone who found themselves here, at this point, we are still looking into this issue.  By "we", I mean ServiceNow.  If we get it fixed, I'll post the solution here.
