Cannot access a closed file

[kilasuit]

I'm occasionally getting this error on running Invoke-ScriptAnalyzer with v 1.6.0

Invoke-ScriptAnalyzer : Cannot access a closed file.

This seems only to fire occasionally on the following rules with the error message given above

PSUseToExportFieldsInManifest
PSMissingModuleManifestField

@kilasuit Thanks for the full error object. Looks like something is going awry in GetModuleManifest method. And from your observation looks like this happens only occasionally. Can you provide me any more information such that I can reproduce this on my end?

[kilasuit]

@kapilmb - sorry on delay on getting back to you.

It seems to be on random runs of the Script Analyzer where this issue occurs.

Simplest way I've found to see this occur it is by running something like the below

1..20 | Foreach { Invoke-ScriptAnalyzer -path .\test.psd1 }

@kilasuit No worries. I still am not able to reproduce the error, even after iterating for 1000 times.

A few questions -

1. What version of PSScriptAnalyzer are you using?
2. Does the error show up only for module manifest PSD1 files or any PSD1 files?

[kilasuit]

1. I'm getting it in 1.5 & 1.6
2. Only tested on module manifest psd1 files

Also I get this on a few different machines - I think that there is an issue with the underlying runspace that is used being closed to early (or not correctly)

I'd be happy to email over some PSTranscripts if that would help diagnose at all?
