ERROR initialize:initialize: failed to add schemas from catalog

[Spitfire1900]

Getting the following error in the Even Better TOML LSP output pane:

That doesn't help anything.

Please provide a minimal but runnable online reproduction.

[Spitfire1900]

Unfortunately, this is all the output that's available in the even better TOML output pane in VScode. I have also been unable to reproduce it on other workstations.

[JounQin]

Based on fetch failed, it could just be a request error.

[Spitfire1900]

I am behind a corporate web proxy in this scope. I've worked with our IT Security department to allow-list the schema catalog, but I can't be certain that the web proxy is the issue when the fetched resource that failed isn't dumped to console.

I have the same trouble for 3 days. I tried to reinstall the plugin, but it doesn't work. I even tried running it on Ubuntu WSL.

There's nothing output in Even Better TOML output pane.

When I modify the config of the plugin, a new warning appears:

 WARN no notification handler registered method=$/setTrace

I have no idea about this problem.

Windows 11, VSCode 1.91.1, Even Better TOML 0.19.2

I'm experiencing the same issue behind a corporate proxy, so I dug in:

The root cause appears to be undici not respecting HTTP_PROXY/NO_PROXY etc. env vars, fixed here.

The fix was released with undici v6.14.0, which in turn made it into nodejs v22.

I reckon upgrading to nodejs v22 should fix the issue (though I'm ill-equipped to do so at this time).

I am seeing the same thing. I suspect it is due to ZScaler being rolled out in our company - at least when I turn off ZScaler, this error goes away (and is replaced by another, hopefully unrelated one). But without knowing which URL fails, I have no way of knowing how to work with IT to get this unblocked. Again, I suspect it's one of the following, but those all work fine in the browser and using curl:

• https://www.schemastore.org/api/json/catalog.json
• https://json.schemastore.org/pyproject.json

External fetches should really be logged, at least in error cases. The magic happens here: if anyone knows rust, please send a PR hacking in some debug output :)

It seems that this problem only happens in VSCode stable version. After switching between the two versions of VSCode several times, I have been using it very well in VSCode Insider for about 3 months.

setx NODE_EXTRA_CA_CERTS Path\To\ZScaler-Root-CA.pem fixed the issue for me.
