Oracle APEX: Error: SyntaxError: Unexpected end of JSON input

Ok, so I get this problem too, It's when I submit the page but instead of reload the whole page, I'm running a process and stay there.

The process itself works well, however I get the error message, just like you.

So I don't get the a solution, but found a workaround by adding this to the end of my process:

    apex_json.open_object;      apex_json.write('success', true);      apex_json.close_object; 

You are missing the page number on :COMPANY_NAME. It should be something like :P1_COMPANY_NAME

I was encountering a similar error when operating the last page in a chained dialog (aka "wizard") I had created.

The cause of my issue was that I had created a branch on the "After Submit" with the Behaviour/Type attribute set to "PL/SQL Procedure" and then had the code I wanted to be executed within the PL/SQL code attribute. When the "Finish" button was clicked, I was seeing the same error.

My resolution was to delete the branch and instead to use Create Process, with the Identification/Type set to "PL/SQL Code" and then placing the code I wanted to be executed within the "Source/PL/SQL Code" attribute.
