NuGet behind a proxy

Hey I am in the process of releasing a .NET project as a Docker container. How can I configure Nuget to use the proxy from the HTTP_PROXY & HTTPS_PROXY environment variables? Currently it fails on restore as it can't resolve the feed. Current Dockerfile:

FROM mcr.microsoft.com/dotnet/runtime:6.0-alpine AS base
WORKDIR /app

ENV HTTPS_PROXY ${HTTPS_PROXY}
ENV AZURE_DEVOPS_ACCESS_TOKEN ${AZURE_DEVOPS_ACCESS_TOKEN}
WORKDIR /src
RUN dotnet nuget add source --name "my_feed" --username unused --store-password-in-clear-text --password ${AZURE_DEVOPS_ACCESS_TOKEN} "http://my_feed.tld/nuget/v3/index.json"

LINQ Lambda-Expression Diff

It's probably very simple, I'm just on the fence today. The Lambda version works as expected the Expression version does not. Do you see where the difference is? Works:

var groupedOccurences = occurences
                    .SelectMany(static occurence => occurence.MailAddress.Split(',', StringSplitOptions.RemoveEmptyEntries).Select(addr => new
                    {
                        MailAddress = addr.Trim(),
                        occurence.DatabasePath,
                        occurence.MaskName
                    }))
                    .GroupBy(static occurence => occurence);

var groupedOccurences = occurences
                    .SelectMany(static occurence => occurence.MailAddress.Split(',', StringSplitOptions.RemoveEmptyEntries).Select(addr => new
                    {
                        MailAddress = addr.Trim(),
                        occurence.DatabasePath,
                        occurence.MaskName
                    }))
                    .GroupBy(static occurence => occurence);

Does not work (different results):

var groupedOccurences = from occurence in occurences
                        from address in occurence.MailAddress.Split(',', StringSplitOptions.RemoveEmptyEntries)
                        group new {
                            MailAddress = address.Trim(),
                            occurence.DatabasePath,
                            occurence.MaskName
                        } by occurence into grp
                        select grp;

var groupedOccurences = from occurence in occurences
                        from address in occurence.MailAddress.Split(',', StringSplitOptions.RemoveEmptyEntries)
                        group new {
                            MailAddress = address.Trim(),
                            occurence.DatabasePath,
                            occurence.MaskName
                        } by occurence into grp
                        select grp;
