Problem trying to add via Unity package manager

[Froghut]

When I try to add the package via Unity package manager I get the following error:

[Package Manager Window] Cannot perform upm operation: Unable to add package [https://github.com/handzlikchris/FastScriptReload.git?path=Assets]:
  Manifest [C:\Work\vampiresurvivors\Library\PackageCache\com.handzlikchris.fastscriptreload@f68663e6cd\package.json] is invalid:
