Generated model ctors aren't valid

[bc3tech]

I'm trying to generate with this command

npx @openapitools/openapi-generator-cli generate -i https://www.thebluealliance.com/swagger/api_v3.json -g csharp --library httpclient --additional-properties=packageName=TheBlueAlliance.Api,nullableReferenceTypes=true,useDateTimeOffset=true -t /mnt/e/gh/me/openapi-generator-csharp-system-text-json

the resulting models have invalid ctors:

/// <summary>
/// Initializes a new instance of the <see cref="APIStatus" /> class.
/// </summary>
/// <param name="">Year of the current FRC season. (required).</param>
/// <param name="">Maximum FRC season year for valid queries. (required).</param>
/// <param name="">True if the entire FMS API provided by FIRST is down. (required).</param>
/// <param name="">An array of strings containing event keys of any active events that are no longer updating. (required).</param>
/// <param name=""> (required).</param>
/// <param name=""> (required).</param>
public APIStatus(int  = default(int), int  = default(int), bool  = default(bool), List<string>  = default(List<string>), APIStatusAppVersion  = default(APIStatusAppVersion), APIStatusAppVersion  = default(APIStatusAppVersion))
{
    this.CurrentSeason = ;
    this.MaxSeason = ;
    this.IsDatafeedDown = ;
    // to ensure "" is required (not null)
    if ( == null)
    {
        throw new ArgumentNullException(" is a required property for APIStatus and cannot be null");
    }
    this.DownEvents = ;
    // to ensure "" is required (not null)
    if ( == null)
    {
        throw new ArgumentNullException(" is a required property for APIStatus and cannot be null");
    }
    this.Ios = ;
    // to ensure "" is required (not null)
    if ( == null)
    {
        throw new ArgumentNullException(" is a required property for APIStatus and cannot be null");
    }
    this.Android = ;
}

notice the lack of parameter names

not sure what to do to fix this; I'm unfamiliar w/ mustage/handlebar syntax to know if/where/how it can be fixed.
