CB Autoaction stream ability

Hello
I use a CB Code autoaction to securely connect to a php file including a call to openAI API

Action : include_once(JPATH_ROOT . '/ahatools/activations/assets/OpenAiCB.php');

The autoaction is configured to output the result of the file with the following lines

Output : PHP
header('Content-type: text/event-stream');
header('Cache-Control: no-cache');

The autoaction seems to work fine by getting the data from the php file but it does not seem to be streamed as everything is received in one shot.

Does autoactions support stream ? would they stream the output to the html this way ?

Thanks for your ideas 

Check the response headers in your request to the auto action URL. Be sure you're accessing the URL with &format=raw in the URL to try and limit the headers being overridden. If the response header is correct the issue isn't with the code, but with whatever you're using to subscribe to the server side event.
