`New-PSUEndpoint -Regex` results in 404

I’m trying to create the following API endpoint:

New-PSUEndpoint -Url '^foo\/bar(?<varA>\/subpath|)' -Regex -Endpoint {
    Param(
        [string]$varA
    )

    [...]
}

The new endpoint does show up in the Admin interface, but when trying to access it, I get a 404 response for both localhost:5000/foo/bar and localhost:5000/foo/bar/subpath

In Windows eventlogs, I do not see any useful error I can troubleshoot with. What am I doing wrong?

Product: PowerShell Universal
Version: 2.5.3

You need a slight adjustment to your regex since the ‘/’ is included in the path it’s trying to match.

New-PSUEndpoint -Url '^\/regex\/works' -Regex -Endpoint {
    "regex"
}

New-PSUEndpoint -Url '^\/foo\/bar(?<varA>\/subpath|)' -Regex -Endpoint {
    Param(
        [string]$varA
    )

    $VarA
}

Here’s how I’m calling and validating them. Notice that the subpath contains the forward slash.

        It "should work with regex with params" {
            Invoke-RestMethod http://localhost:5000/foo/bar/subpath | Should -Be "/subpath"
        }

        It "should work with regex" {
            Invoke-RestMethod http://localhost:5000/regex/works | Should -Be "regex"
        }

I actually also tried that syntax with the escaped slash in front, but I’m still getting 404 response, and no error anywhere.

I tried with or without -ErrorAction Stop, but nothing changes.

Can you do me a favor and crank up your log level to debug and send it my way? It seems like it should be finding these paths.

Shameless bump; do the logs help you in any way to see what’s happening?
