`TypeError: 'NoneType' object is not subscriptable` (`self.hist = self.cli.history(self.img['RepoTags'][0])`)

Traceback (most recent call last):

TypeError: 'NoneType' object is not subscriptable

I think the problem is that I pulled an image as a sha256:xxx instead of a tagged one

same.

[johndpope]

you can use

   self.hist = self.cli.history(self.img['RepoDigests'][0])

[johndpope]

you can easily debug with python - just set the args with image id.
