Fix New-SignalChart to throw terminating error when Values is null by Copilot · Pull Request #29 · AsBuiltReport/AsBuiltReport.Chart

Copilot · 2026-03-14T14:41:56Z

New-SignalChart was calling WriteObject with an error string when Values is $null, causing Should -Throw Pester tests to fail and making error handling inconsistent with other cmdlets.

Change

Sources/PowerShell/SignalChartPwsh.cs: Replace WriteObject("Values parameter cannot be null or empty.") with ThrowTerminatingError using an ArgumentException, matching the pattern used elsewhere in the codebase.

// Before
WriteObject("Values parameter cannot be null or empty.");

// After
ThrowTerminatingError(new ErrorRecord(
    new ArgumentException("Values parameter cannot be null or empty."),
    "ValuesNullOrEmpty",
    ErrorCategory.InvalidArgument,
    null));

Pull request overview

This PR updates the New-SignalChart PowerShell cmdlet to emit a terminating error (instead of writing an error string to the pipeline) when -Values is passed as $null, improving error handling behavior for callers and Pester tests.

Changes:

Replace WriteObject("Values parameter cannot be null or empty.") with ThrowTerminatingError(...) using an ErrorRecord and ArgumentException.
