Save failed, and an internal error occurred.

Hi, Thank you for developing this plugin.
I installed the STAX Header Builder Plugin (v1.0.5), clicked “Open STAX Builder” on the admin bar, and moved to the Builder page.
Then, I clicked the SAVE button (floppy icon) at the bottom right of the page, but the message “Internal error. Please try again.” Was displayed on the upper right of the page, and saving failed.

When I check the Google Chrome Console, an exception has occurred.
Here is the log… How can I use this nice plugin?
