When calling:

 

Plsql_Rest_Sender_API.Call_Rest_EndPoint_Empty_Body(
                                                             rest_service_ =>'search',
                                                             url_params_ => url_params_,
                                                             callback_func_ => 'my_util_api.my_callback_proc’
                                                             http_method_ => 'GET',
                                                             sender_           => 'CONNECT',
                                                             receiver_         => 'MY_RECEIVER’',
                                                             fail_notify_         => TRUE,
                                                             failed_callback_fun_ => 'my_util_api.rest_error',
                                                             accepted_res_codes_  => '200,404');

 

I get ‘No output from address line in previous chain link; cannot proceed.’

 

I originally tried this call without accepted_res_codes as I wanted it to callback rest_error on 404, but then attempted with the accepted_res_codes to see if that would work.  It works perfectly when the response code is 200 just not 404.

 

Any ideas on what I am doing wrong?

I figured this out:

 

The failed callback creates a background job with argument type ‘Normal Parameter’. As such, the callback procedure must contain the correct parameter names, which does not seem to be anywhere in the documentation.

 

The correct format for the fail callback procedure is:

 

PROCEDURE my_fail_callback(error_text_ IN VARCHAR2, app_message_id_ IN VARCHAR2)
