Documenter.jl: Link to Source not working

General Usage
1

Hi,
I’m using Documenter.jl to create my documentation. However, the “Link to Source”, which is available in every HTML-page, where i reference to some function of my package, is broken. It actually appears, but just links to the repo itself, instead of the file and line of code of this function.

What could be the cause of this behavior? I’m using Azure DevOps with the following configuration:

    format=Documenter.HTML(;
        prettyurls=get(ENV, "CI", "false") == "true",
        canonical="https://dev.azure.com/Org/Repo/_git/MyProject.jl",
        edit_link="master",
        assets=String[],
        repolink="https://dev.azure.com/Org/Repo/_git/MyProject.jl"
    ),

My deployment configuration (to work on Azure DevOps) is as follows:

# For deploydocs, you need to set up the following TRAVIS_* environment variables.
withenv(
    "TRAVIS_REPO_SLUG" => get(ENV, "BUILD_REPOSITORY_NAME", nothing),
    # Dirty hack
    "TRAVIS_BRANCH" => "master",
    # "TRAVIS_BRANCH" => get(ENV, "BUILD_SOURCEBRANCH", nothing),
    # Is true, but should be a decision criterion, like: "get(ENV, "BUILD_SOURCEBRANCH", nothing)"
    "TRAVIS_PULL_REQUEST" => ("SYSTEM_PULLREQUEST_PULLREQUESTID" in keys(ENV)) ? "true" : "false",
) do
    deploydocs(
        repo = "git@ssh.dev.azure.com:v3/Org/Repo/MyProject.jl",
        deploy_config = Documenter.Travis(),
        devbranch="master",
        branch="do-pages"
    )

Best
