When posting a comment without an image, the comment is not made

When posting a comment without an image, the comment is not made.
When posting a comment with an image, the comment IS made and there is no problem.

Steps to reproduce this behavior:

• Login (register if you have no account yet)
• Comment on a post with only text and no image
  (create a post or run npm run db:generate 100 in the /express/ directory.)

In the browser console the following response appears:

Object { success: false, message: "Post must include content" }

The server terminal logs the following:

field name post_id
field value bed5f54c-0d8e-4241-bf78-c60266bf660d
field name comment_text
field value test
field name context
field value comment
formdata on close [Object: null prototype] {
  assignedEntryId: 'ca027bb2-4515-473d-9158-0d3325f9c666',
  post_id: 'bed5f54c-0d8e-4241-bf78-c60266bf660d',
  comment_text: 'test',
  context: 'comment'
}
