3.0.1

Describe the bug

This isn't a request for any particular behavior, just capturing the user experience.

When testing an activity type with an Instant-type parameter, we found that our InstantValueMapper is incapable of serializing the value of Instant.MIN, which was set as the default value. When placing this activity on the timeline, the UI displays that the activity has no parameters. The problem wasn't explained in any meaningful way in the UI except for a Error: Invalid arguments for input type "<activity type>" warning in the logs at the bottom of the page. The stacktrace in the merlin server logs were useful.

Reproduction

Set a default value on an activity parameter that breaks the value mapper.
