Cannot convert value 'PSDepend.Format.ps1xml' to type 'System.Version'.

[justinainsworth]

I am working on an azure devops pipeline, and utilizing PSDepend to prefetch build dependencies on a self hosted build environment.

I have noticed that when invoke-psdepend is called using an input object (using the installimport-hashtable parameter set), it is failing with the following error:
Cannot convert value 'PSDepend.Format.ps1xml' to type 'System.Version'

Error Record and stack trace below:

I ran invoke-psdepend in verbose mode, and got this additional output:

Any ideas on what is going on here?
