I was able to work around the issue by completly deleting the 'servers' paramter from the foreman.

I then uninstalled and reinstalled the module, which appears to have reset all the parameters back to defaults.

This still is a bug, the foreman shouldn't have let me put invalid parameters in, or atleast should have let me undo my mistake, not crash.

Stumbled on the same issue. Fix for me was to provide default value for the type. For example for arrays you should enter [] for empty array. Maybe when changing type Foreman should also provide default 'empty' value for non-string types?

Just hit this bug as well. Unable to work around this issue because I am using the use puppet default feature which greys out the default value.

I have noticed this when the parameter value in the puppet code is set to an inherited value like $class::params::value1. Foreman thinks this is a string but it should be rendered as a variable which could be any type. Currently there is no way for foreman to check the type of the inherited value so it gives up and sets it to a string.

Actually, the work around for anyone also using the "use puppet default" feature is to do the following:

1. click override
2. keep use puppet default UNCHECKED
3. change the default value to a default value you want. Example for Array: [], Example for Hash: {}
4. change the parameter type to match your default value array = [], hash = {}
5. click submit
6. Go back and edit, and then check use puppet default (only if you desire this setting)
7. click submit (again)
