CRM Client Script not running anything after function.execute

CRM Client Script not running anything after function.execute

Inside my client script im calling a function;

var response2 = ZDK.Apps.CRM.Functions.execute("Books_send_quote", parameters);

The function is working, doing everything it should. The function logs also show successfull runs with the correct output.
But anything I try to run after this line of code doesnt work:
  log(4);

Even a simple log doesnt run after this code, im calling another function earlier in my script which works as usual. When i manually run the function it takes about 10 seconds, but it works. Are the 10 seconds too long for ZDK?

What would I need to do to run more code after calling this function?

Thanks.
