RangeError: Invalid time value

[jazbogross]

When I create a new post I get an error in the preview window with the following console output:

cms.be93d.js:120 RangeError: Invalid time value at ne (cms.be93d.js:120:2229572) at pe (cms.be93d.js:120:2233729) at xa (cms.be93d.js:120:2121097) at xl (cms.be93d.js:120:2177952) at bc (cms.be93d.js:120:2167104) at vc (cms.be93d.js:120:2167032) at Oc (cms.be93d.js:120:2166895) at ac (cms.be93d.js:120:2163702) at oc (cms.be93d.js:120:2162254) at k (cms.be93d.js:120:2195364)

Once I enter info into the frontmatter fields and save I get a working preview. There is no problem when editing existing posts. The error only happens at the first instance of creating a new post. I know that open authoring is in Beta, but this was happening before I changed to editorial workflow.

To Reproduce I created this from the Hugo template. I have made content and layout changes but everything else remains the same and the problem was there before the changes I made so I would think the issue is there from the beginning when spinning up a site from the Hugo template.

Expected behavior Preview of the changes made in frontmatter on a new post. No error message.
