Docker Extension VSC - "failed fetching" error when executing "Run and debug" on a container

[adijian (adijian)]

On version 1.29.2 there is an issue running and debugging a containered .NET app.
A pop up message saying "failed fetching" appears with no further information.

Encountered when following this guide: https://code.visualstudio.com/docs/containers/quickstart-aspnet-core

No issue on version 1.23.0.

Can you share a screenshot?

[adijian (adijian)]

No, nothing, it initally pops up acquiring .net debugger, then it says fetch failed

[Brandon Waterloo [MSFT] (bwateratmsft)]

Sounds like it's failing to get the VSDBG download script. Are you behind a restrictive firewall or proxy?

[adijian (adijian)]

nope, happens on my personal pc out of work as well!

[Brandon Waterloo [MSFT] (bwateratmsft)]

If 1.23.0 is working this is probably a consequence of the change from node-fetch to plain old fetch. I'll look at adding some additional logging here so we can better figure out what is going on.

I created #4378 to track that.
