Help with Flows for apex application: Unexpected end of JSON input

[lipe-8haus]

Whenever I try to perform any kind of action trough the flow monitor or flow management Interactive report action menu, I get the error "Error: SyntaxError: Unexpected end of JSON input"
I am more of a PL/SQL developer than a javascript developer, so my knwoledge about javascript is limited.

I believe its something I forgot to configure

this is the call stack of the error

my application is open for access

Thanks!

I got it to work,
there is a application process named "[AJAX_HANDLER]" that run only if is not a public user, so I changed the Authentication Schemes from "No Authentication" to "Oracle Apex Account" and it worked fine
