File names in extension can no longer contain spaces?

It didn’t use to be a problem when packaging extensions, but since 0.3.40 I’m getting the error below:

error: Part Name 'vsts-snyk/node_modules/snyk/Contributor Agreement.md' is invalid. Please check the following: 
error: 1. No whitespace or any of these characters: #^[]<>?
error: 2. Cannot end with a period.
error: 3. No percent-encoded / or \ characters. Additionally, % must be followed by two hex characters.
tfx failed with error: Error: C:\TFS\_W\3\s\node_modules\.bin\tfx.cmd failed with return code: 4294967295

Since I cannot enforce this kind of restriction on developers of 3rd party dependencies, it’s a very inconvenient change.

Issue still open?

To get around this problem we have been running an in-line Powershell script prior to running the VSIX packaging step.

The code is as follows

dir -recurse | where {-Not $_.PsIscontainer -AND $_.name -match " "} | foreach { 
    $New=$_.name.Replace(" ","_")
    Rename-Item -path $_.Fullname -newname $New -passthru
}
