Bug: TypeError: fetch failed when using proxy

[lindeberg]

What happened?

We get the error

Warning: Error while fetching latest Helm release: TypeError: fetch failed. Using default version v3.13.3

when using v4.2.0 on a self-hosted runner with http proxy.

It seems that the proxy is not being used. Is proxyAgent not set using undici?

Version

• [X] I am using the latest version

Runner

self-hosted, linux

Relevant log output

2024-09-04T11:38:09.8209789Z Runner is running behind proxy server '<secret>' for all HTTP requests.

Appears to be an issue with resolving get.helm.sh. Started working again for me.
