mobilesafari sandbox deny error with iOS action extension

I'm developing an action extension with iOS 9.3. I need to send a selected text from safari to the action extension. But sometimes the extension doesn't received any text from safari. Device console shows the following message. It seems that safari couldn't access to the javascript file.

May I have any suggsion for this issue?
