In some cases where a module is loaded with
using module <path>
and there is an error loading the module, we can end up with a case where PowerShell HadErrors is true, but there are no errors in the powershell.Streams.Errors.
This causes an index out of range when we try to throw.
var commandInfo = new CmdletInfo("Import-Module", typeof(ImportModuleCommand));
var ps = PowerShell.Create(RunspaceMode.CurrentRunspace)
.AddCommand(commandInfo)
.AddParameter("Name", modulePath)
.AddParameter("PassThru");
var moduleInfo = ps.Invoke<PSModuleInfo>();
if (ps.HadErrors)
{
var errorRecord = ps.Streams.Error[0];
throw InterpreterError.NewInterpreterException(modulePath, typeof(RuntimeException), null,
errorRecord.FullyQualifiedErrorId, errorRecord.ToString());
}I haven't figured out yet what is causing the error, and it is harder to diagnose since this error masks the underlying condition.
Steps to reproduce
# mod.psm1
$c = Get-Command -CommandType Application -Name Foobar.nonexisting -ErrorAction SilentlyContinue
######
PS> using module .\mod.psm1
Expected behavior
get-command : The term 'Foobar.nonexisting' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At mod.psm1 line:1 char:1
+ get-command nonexisting -CommandType Application
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (nonexisting:String) [Get-Command], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException,Microsoft.PowerShell.Commands.GetCommandCommand
Or some
Actual behavior
An error occurred while creating the pipeline.

This is a really unhelpful error message :)
