Dashboards not starting with default env (Request failed with code 500)

PowerShell Universal
1

Made a change to the environments.ps1 on accident and it erased all my pre-configured environments.
Since then I just duplicated what I had on my other test box which looks like the following:

I set the default environment to 7.1.3 under settings / general

I can change the environment per dashboad to use 7.1.3 and they start fine. However when I use “default” they throw the following error. I can not create new dashboards either. Kind of stuck.

This kind of seems like a bug. You might need to set the environment to 7.1.3 for the dashboard for now while we investigate. I’ll open an issue to track this case.

That said, we just did some work around environments in 2.3 because of an issue there so it may be resolved already but it had to do with APIs and the default environment. I’ll validate that fix for this case as well.

Sounds good. Working on getting that server restored from a nightly backup in the meantime.

@adam @mikedhanson I had this same issue yesterday out of nowhere right after stopping the dashboard but managed to get it back working. I did the following; my env is IIS

Deleted dashboard
Stop app pool
Stop web site
Open PS in admin mode
Ran the get-childitem FOLDERPATH -recourse | unblock-file
Recreated the dashboard

However, my 500 error apparently was related to a supposedly missing js file.

Hope this help a bit

i had the same issue right after i installed the latest version (3.1.6). spent like half a day just to troubleshoot. i reverted to the previous version installed on my psu (2.11.1) and worked fine.
