on delete TypeError: text.replace is not a function fileinput.js

[Bintux]

Prerequisites

• I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• The issue still exists against the latest master branch of bootstrap-fileinput.
• This is not an usage question. I confirm having read the plugin documentation and demos.
• This is not a general programming / coding question. (Those should be directed to the webtips Q & A forum).
• I have attempted to find the simplest possible steps to reproduce the issue.
• I have included a failing test as a pull request (Optional).

Expected behavior and actual behavior

When using the delete function and my back-end page returns an error in the described json format: {error: BOOLEAN_VALUE} I get the error :
