API - Get with $select=Owners returns "an error has occurred"

[o-l-a-v]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest version
• Search the existing issues.

Steps to reproduce

To reduce load on PSGallery and increase speed I'd like to use $select to only request the properties I need.

This works for properties like Id, Version and Authors. But not for Owners for some reason.

URL with all properties:

• https://www.powershellgallery.com/api/v2/Packages()?$filter=startswith(Id,%27Az.%27)%20and%20IsLatestVersion%20and%20not%20IsPrerelease&$orderby=Id%20asc

URL with Id and Version (works):

• https://www.powershellgallery.com/api/v2/Packages()?$filter=startswith(Id,%27Az.%27)%20and%20IsLatestVersion%20and%20not%20IsPrerelease&$select=Id,Version&$orderby=Id%20asc

URL with Id, Version and Owners (does not work):

• https://www.powershellgallery.com/api/v2/Packages()?$filter=startswith(Id,%27Az.%27)%20and%20IsLatestVersion%20and%20not%20IsPrerelease&$select=Id,Version,Owners&$orderby=Id%20asc

Expected behavior

All properties should be possible to $select

Actual behavior

$select=Owners does not work

Suddenly today the API does not allow to $select any property. This fails with error "This request is blocked by a Web Application Firewall rule.":

• https://www.powershellgallery.com/api/v2/FindPackagesById()?id=%27Az.Accounts%27&$filter=IsLatestVersion%20and%20not%20IsPrerelease&$select=Authors,Published,RequireLicenseAcceptance,Tags,Version&semVerLevel=1.0.0

Removing $select succeeds:

• https://www.powershellgallery.com/api/v2/FindPackagesById()?id=%27Az.Accounts%27&$filter=IsLatestVersion%20and%20not%20IsPrerelease&semVerLevel=1.0.0

Edit: Works again now.
