Javascript change Incorrect message at runtime.

Just in case anyone comes across this in the future. The problem is two fold. 

1. Captivate stores this data as Images not text. It then renders this to a canvas. It then puts a div on top of that canvas with text for screen readers / accessability. 

2. The data is not stored in a way that is super distinct from other elements like buttons ect. No unique class name ect.

here is what worked for me. Note this is only for changing the default incorrect message to some other message. This assumes you want to change them all and not have unique fail messages for difference slides.

I needed to do this because my company wanted to change the message across all of our already published courses and opening / re exporting every single course we have in captivate would have taken days.

for (let key in cp.model.data) {
  let value = cp.model.data[key];
  console.log(value.accstr);
if(value.accstr == "Incorrect - Click anywhere to continue. "){
value.ip = "https://companywebsite.com/newIncorrectMessage.png"
value.accstr = "New incorrect message"
}
}
