I'm having an issue where I've got a button that's action is to 'submit page' upon being clicked. The code then executes a PL SQL statement:

```
IF :REQUEST = 'btn_create_company' THEN
    INSERT INTO COMPANIES (company_name) VALUES(:COMPANY_NAME);

```

However, when the code comes to execute, whilst it is adding the entry to the database, I'm getting this error on the client which is preventing the page from redirecting after processing: 

> 
> Error: SyntaxError: Unexpected end of JSON input
> 
> 
> 

I don't understand why this is happening as I'm confident there's nothing wrong with the above statement.
