System.InvalidOperationException: 'Could not find color or style '0'.

Caused by this

 AnsiConsoleExtensions.Log($"Data[0]: {_data[0]}", "info");

basically

AnsiConsole.MarkupLine($"[white]{timeStampFull}-{severity.ToUpper()}:[/] {message} [white]...[/]");

doesn’t like the extra braces but why should that matter?

the number of opening markup tokens should matchup the number of closing tokens, if there are more then these are likely part of the message even more so if they contain no valid markup tag

You’ll have to escape it with either mystring.EscapeMarkup() or Markup.Escape(myString).

See the section “Escaping format characters” at https://spectresystems.github.io/spectre.console/markup for more information.

It just occurred to me that it’s probably related to the dictionary keys and values I’m using:

Config.ToTokens().ToDictionary(entry => entry.Key, entry => entry.Value.ToValueString()).ToJson();

Yields:

{
  "Commands.Deploy.Repair[0]": "code.cmd",
  "Commands.Deploy.Repair[1]": "--new-window",
  "Commands.Deploy.Repair[2]": "--wait",
  "Environment.Name": "alpha",
  "Environment.DisplayName": "Alpha",
  "Environment.Type": "Development",
  "Environment.CostCenter": "Beacon",
  "Environment.Aws.AssumeRoleArn": "arn:aws:iam::REDACTED:role/deployer",
  "Environment.Aws.AccountId": "REDACTED",
  "Environment.Aws.Region": "us-west-2",
  "Environment.Aws.Ec2.InstanceType": "t3.medium",
  "Environment.Aws.Ec2.KeyName": "beacon-oregon",
  "Environment.Aws.Eks.AutoScaling.DesiredCapacity": "1",
  "Environment.Aws.Eks.AutoScaling.MinSize": "1",
  "Environment.Aws.Eks.AutoScaling.MaxSize": "1",
  "Environment.K8s.Version": "1.20",
  "Pulumi.Organization.Name": "pharos",
  "Pulumi.Organization.DisplayName": "Pharos"
}

And I’ve just confirmed that EscapeMarkup fixes it. 😊
