This option is after the release of version 6.5.

Yeah, it sounds like you're not using 6.5. You're probably using the latest master instead.
Thanks for your answers, according to the system, yes, the installation file of the official version does not yet contain these changes? Or do I have to copy the code again?
You have to use matching web app and backend.
I'm using the latest version on front and back!!
Are you using official release or you're using the latest source code? Those are very different incompatible things.
Dear, I am using the official version as I have not had time to review the source code.
The error clearly indicates that you're not using the official release of the web app.
I have reinstalled the system to review what you say... but it remains the same... is to do what Cristian says to have if the failure is resolved.
are you using these installers?

Right, that's what I'm using....
No, you're not.
I agree with Anton, you are omitting to describe something.
This is the 6.5 version code for creating notifications and it does not have the option to add a description in the source code.
There's a possibility that you forgot to clear the cache.
Hello friends, I hope you are well.
Today I updated to 6.5. But every time I add a description in the Extra option, I get the error that the image is missing. I appreciate your support.
Regards.
