• PowerShell
• Xamarin.Android (build project)
• MSBuild (build tests)
• .NET Core (test tests)
• Android Signing
• Publish Build Artifacts
• Google Play - Release (https://marketplace.visualstudio.com/items?itemName=ms-vsclient.google-play)
• PowerShell

Steps to recreate

1. Export the build definition from a VSTS account
2. Log in in a different VSTST account
3. Go to Builds
4. Click Import
5. Choose the export file and click Import

Current behavior

After the import an error is shown: Cannot read property 'length' of undefined

Expected behavior

No error should be shown, the build definition should be correctly imported

Additional information

The marketplace build tasks "Version assemblies" and "Google Play - Release" have been added to the targtet VSTS account before trying to import the build definition.

This issue can be closed. It was caused by using the wrong (built-in) import functionality of VSTS, which uses a different JSON structure.
