Exception raised when supplying invalid json format

[daviddavis]

When modifying a repository version, you get an exception message if the json format isn't a list of hashes.

Steps to reproduce:

pulp file repository create --name test2
pulp file repository content modify --repository test2 --add-content '{"sha256": "abc123", "relative_path": "test"}'

Exception:

TypeError: find() argument after ** must be a mapping, not str

I am marking this a bug only, because the documentation of this parameter is already rather explicit, but stacktraces are not suitable for users.

To solve it, should we just verify it's a list, or should we add a complete schema validation framework?

[daviddavis]

That's a good question and I don't have a strong preference.

[mdellweg]

We want to add some sort of validation in the cli at least.
