Request initialize failed with message - scheme is missing

[clarkbreyman]

WORKAROUND

If you are experiencing this, try opening a folder first, then open the Azure Pipelines file you want to view.

---

Experiencing failure on YAML load. I am signed in with my @microsoft account. I have tried uninstalling, quit and restart but that has not helped.

Request initialize failed with message: [UriError]: Scheme is missing: {scheme: "", authority: "", path: "null", query: "", fragment: ""}

Granting full disk access to VSCode did not resolve.

Same issue here.

Interestingly, the Output panel has two entries for Azure Pipelines Language.

Other than the message popping up, what else happens? Do you still have IntelliSense/auto-completion?

No, I do not.

No IntelliSense. The only completions offered are words that already exist in the file.

And can I also get the output from the Azure Pipelines channel? (Ctrl+Shift+U, switch to Azure Pipelines)

[sharpjs]

With this minimal pipeline:

steps:
- pwsh: Write-Host "Hello, world."

With all extensions disabled except:

• Azure Pipelines 1.247.2
• Azure Resources 0.9.9

I get the error every time VS Code launches.

Note regarding my Azure tenants and subscriptions

Not sure if this matters, but just in case. Entra tenants:

• Main corporate tenant.

  • I'm some sort of contributor here.
  • VS Code, Teams, Az module, Azure CLI, etc. are signed in to this tenant.
  • WAM is signed in to this tenant.
  • Computer is not domain-joined.
  • Has Azure subscriptions, but I don't touch them.
  • Signing in does MFA dance with Okta.

• My business unit's test/dev tenant.

  • Trusts the main corporate tenant.
  • My corporate identity is an owner here.
  • Has one subscription. Azure DevOps and I manage resources here.
  • Touching this does separate MFA dance with Entra via its 'security defaults'.

• My business unit's production tenant.

  • Trusts the main corporate tenant.
  • My corporate identity is an owner here.
  • Has two subscriptions. Azure DevOps and I manage resources here.
  • Touching this does separate MFA dance with Entra via its 'security defaults'.

1.249.0 was released last night. I'm curious if any of you are still seeing this error - mostly because we didn't introduce any changes in this area for the previous 1.247.1 release, so I'm wondering if it'll just "fix itself" for this release :D.

If not, I'll keep investigating (specifically, the double "Azure Pipelines Language Server" output looks suspicious).

[sharpjs]

After the update to extension 1.249.0, the problem persists. I believe I've been experiencing this error for quite some time — in fact, ever since #583 was resolved. That is at least consistent with there having been no work in that area for the current release.

The error message now is slightly different:

Initially, there was no duplicate Azure Pipelines Language output channel after updating the extension.

However, I was able to recreate the duplicate channel:

• Press CTRL-SHIFT-P.
• Choose "Developer: Restart Extensions Host".
• Receive "A request has failed. See the output for more information. Source: Azure Pipelines" error.
• Click "Go to output" button.
• Check whether the channel is duplicated.
• Repeat process until duplicated. Most times the result is one channel. Occasionally (say, after 2 to 10 tries) there are duplicate channels. Smells like a race condition. It is suspicious, but it might be unrelated to the issue at hand.

[sharpjs]

FWIW, I polled six colleagues at work, and all six were able to reproduce the issue. We reproduced the issue on both Windows and macOS using both company-provided and personal machines.

[winstliu]

Wow, interesting, okay. I'll dig deeper into this and see if I can add any logging that will help. Thank you for the detailed analysis!

[winstliu]

Aha! I have a repro. Do you by any chance have a workspace folder open in VS Code? Or are you trying to open a file directly? (aka, does View: Show Explorer have a tree view, or does it say no folder opened)

I believe this was caused by this change: microsoft/azure-pipelines-language-server@1e8432b#diff-6ca8c5115f7d741691ab47c62cd9f0dedf4a4dd5cd137a264427c58da9ff9e51R90

Though I wonder why we didn't get any reports on 1.237.0 which is when that change was released.

[sharpjs]

Confirmed! When a workspace folder is open in VS Code, the error does not occur, and the expected IntelliSense appears. When opening the same file directly, the error occurs.

[sharpjs]

Though I wonder why we didn't get any reports on 1.237.0 which is when that change was released.

At least in my case, I might not have edited any pipelines at that time. More generally, I suspect a lot of us users had the initial reaction of hoping the problem self-resolves or gets reported by someone else.

[winstliu]

Excellent, thanks. Since we have a workaround now, I'll target a fix for this in January to give some extra time for the current release to bake and to avoid the possibility of something going wrong with a holiday release.

I should also say this exposes a gap in our tests - all of them currently open a folder :P.

[sharpjs]

Thanks for your attention on this!
