Deno: Cannot work on Azure Web Apps (Windows Server 2016)

[horihiro]

I tried to execute deno on Azure Web Apps (Windows Server 2016, build 10.0.14393.0).
But when executing deno, following error is shown.

Could you please let me know any hints in order to execute deno on Azure Web Apps if there is?

I would appreciate your help.

FYI.
In order to install deno, I fix the script as following before executing install.ps1.

17   "D:\Home\.deno\bin"

94    # [Environment]::SetEnvironmentVariable('Path', "$Path;$BinDir", $User)

It reads like Azure Web Apps doesn't have a FOLDERID_Profile.
https://docs.rs/dirs/2.0.2/dirs/fn.home_dir.html
Can that be set?

Unfortunately this is used/needed even if you pass an explicit DENO_DIR.

Thanks @hayd

Hmm...
I don't know what I should try in order to fix it.

Could you please let me know how to set FOLDERID_Profile if you have any information?

I confirmed that UserProfile already has been set.

Hmm even FOLDERID_Profile isn't set Deno shouldn't panic.

[shibayan]

Azure App Service does not load User Profile by default, so FOLDERID_Profile path resolution fails. This is a problem that can be avoided by setting App Service.

Actually, I'm using the option to load the User Profile (WEBSITE_LOAD_USER_PROFILE), it started without causing a panic.

[horihiro]

Thanks @shibayan !

I confirmed that deno works fine with WEBSITE_LOAD_USER_PROFILE setting, though single core problem (#3466) remains

[horihiro]

shibayan's workaround is very useful.

But it cannot be used for free/shared tier (see https://github.com/projectkudu/kudu/wiki/Configurable-settings#add-user-profile-support-for-a-site).

I think that it needs to be fix about user profile access.

I'm taking a look at this one

[Spoonbender]

It seems this issue no longer reproduces on Deno 1.2.0, perhaps due to fix #6728
It does reproduce on 1.1.3
@horihiro please check and confirm if we can close the issue.

Regarding the repro itself and possibility of testing in integration test:
Theoretically, we should be able to reproduce the issue using the Windows runas command, which allows us to run a process without loading the user profile, for example:

runas /noprofile /user:%USERNAME% "deno.exe run -A test.ts"

However, I failed to reproduce it this way on my machine - further investigation may yield better results.
I did manage to reproduce it on a real Azure Web App, and I can provide my code if that helps.

[horihiro]

I confirmed that [email protected] runs on Azure Web App (win) without WEBSITE_LOAD_USER_PROFILE , including Free SKU.

Many thanks @Spoonbender !
