YAML(786) Unable to load schema

[kaysond]

Describe the bug

I'm getting the following "Problem" on a yaml file.
Unable to load schema from 'https://www.graphql-code-generator.com/config.schema.json': Request vscode/content failed unexpectedly without providing any details.
This is loaded from the default catalog, and I'm able to access the schema via browser and using curl within the vscode terminal. Please let me know how I can help debug.

Expected Behavior

Schema is downloaded without problem

Current Behavior

Schema isn't loaded

Steps to Reproduce

1. Create a file called codegen.yaml
2. Type anything

Environment

• Windows
• Mac
• Linux
• other (please specify)

@kaysond Do you have any VPN/proxy on your laptop?
And make sure that you can access to https://www.graphql-code-generator.com/config.schema.json

[kaysond]

@evidolob I do have a VPN, but it happens even when the VPN is disconnected. I am able to access the URL.

[kaysond]

Interestingly, I'm not seeing any http requests in the vscode dev tools (not sure if extension requests show up there or not...)

I'm experiencing the same issue, but for a different schema;

Unable to load schema from 'https://goreleaser.com/static/schema.json': Request vscode/content failed unexpectedly without providing any details.YAML(768)

I'm able to access the URL just fine using curl (and with web browsers). I'm not behind a proxy.

[kaysond]

@evidolob is it possible to make the extension log the http return code when this fails?

[evidolob]

@kaysond Yes, it is possible

[OutOfFocus4]

I am experiencing this issue, too.

I suddenly have the same error on all files, and like others I can access it manually just fine

Unable to load schema from 'https://json.schemastore.org/github-workflow': Request vscode/content failed unexpectedly without providing any details.

[Vivapercuore]

same error
I fix it by:

• access it manually on browser
• reload IDE window
• done

[diskmanti]

Hello @Vivapercuore ,

I am facing the same issue, can you please explain what do you mean by: access it manually on browser ?

Thank you

[dkirrane]

I don't know if this is related but I see the following warning in Logs (Extension Host)

[2022-06-08 11:44:10.729] [exthost] [warning] [redhat.vscode-yaml] Accessing a resource scoped configuration without providing a resource is not expected. To get the effective value for '[yaml]', provide the URI of a resource or 'null' for any resource.

No issue accessing https://json.schemastore.org/github-workflow.json from my browser.

Hello @dkirrane

I encounter the same issue when I am behind the company proxy, even though I have setup the http.proxy config etc

[dkirrane]

Yip error disappears when I disable proxy on startup code --no-proxy-server

[graham2071]

All schemas fail to load with the following environment:

The extension v1.8.0 is running on WSL Ubuntu-22.04.

I use a VPN. Schemas can be downloaded with browser on Windows and wget on WSL.

Same. It does seem an org proxy rollout maybe be the culprit, but I am not sure how with VS Code and the WSL Remote plugin ...

[shushenghong]

open vpn and test in browser, make sure you can access the url, then reopen vscode

[Blackclaws]

This issue happens to me as well with the gitlab ci schema. Access works fine in the browser and on command line. VSCode fails without even trying to perform a network access.

[Blackclaws]

Ok, so I figured out the issue. The problem has to do with routing. In the specific case I had a route added that falsely routed traffic to the specific ip range that the server hosting the schema in question to a dummy interface ( a mixup of /8 vs /16 subnets ). That was very subtle to debug, and I still don't understand why the browser was able to resolve it fine while Vscode and some other IDEs could not. The fact that other IDEs also failed is what finally clued me in that something else must be wrong.

So I would not discount that this is in fact purely a network issue in your case as well albeit it might be a subtle one.

[JacekArdanowski]

For those who face this issue and are behind corporate vpn and try to host JSON schemas internally:
check if this error disappears when removing TLS. In my case I got rid of https in favour of http and it somehow worked... So my conclusion is that there might be a problem with certificates.

[Ikpambese]

same error I fix it by:

• access it manually on browser
• reload IDE window
• done

this worked for me however am not still sure where this is from

[kamorrissey]

How do I reload the IDE window?

[kaysond]

How do I reload the IDE window?

ctrl+shift+p => developer: reload window

or just quit and restart

I have encountered the same issue and share the same assumption as you. Our company utilizes Zscaler, and I have manually configured the ZScaler root and intermediate CA for Python requests, urllib libraries, as well as npm through environmental variables REQUESTS_CA_BUNDLE, SSL_CERT_FILE, and NODE_EXTRA_CA_CERTS. However, I am uncertain about the specific HTTP request library employed by the extension. To address this problem, it may be beneficial to include an option that allows users to specify the CA. This additional feature could potentially resolve the issue.

[reisman234]

I also encountered this issue for docker-compose files and I had a running VPN connection, but in split mode.

I visited the URL which could not be resolved by the extension, did a reload of the environment, but it did not solve the problem.
Now as a last hope, I downgraded the extension to 1.12.2 which solved the problem in my case.

[akbog]

Encountered this issue because of my Web Application Firewall on my AWS Coudfront distribution. There is a rule configured by default: "name": "awswaf:managed:aws:core-rule-set:NoUserAgent_Header, which blocks requests that don't include a User-Agent header.

Added a custome route that allows requests to pass through for jsonschema files.

Hi, is there a solution to this so far? Experience same error message, no Proxy, no VPN. Workaround with open it manually and refresh didn't work

[yash-phoenix79]

same error I fix it by:

• access it manually on browser
• reload IDE window
• done

This really works, I'm curious on how it works

[lipanpan-hub]

same error I fix it by:

work for me

Same here, our company uses a different product but the result is that the tls certificate is rewritten.
Adding some settings to specify a custom CA can solve the issue.
