Package import fails with murano dashboard

[Ellen Batbouta]

On Friday, July 27th, I pulled down the latest upstream code. Now, I am unable to import a package using the Murano dashboard. I am able to import a package using the CLI. So there is a work around. Here is the error I get when using the dashboard to import a package;

[Kirill Zaitsev (kzaitsev)]

The code in question dates back to 2015. So it's not smth in the code, but rather around it. maybe a new formtools library release?
Can you please post a pip-freeze of your environment? (i.e. a list of python packages installed/used)
