I am using Captivate classic and I have published a project and uploaded to the web. When I run the project I get incesent error messages in console - Uncaught SyntaxError: "[object Object]" is not valid JSON.

This seems to be pointing to the CPM.js and CPXHRLoader.js files.

The main problem is that if i have any custom JS in the project, it will not run any of the functions and the project grinds to a halt. Any suggestions on how to fix this? I have also tried taking out all custom JS and I still get the errors in console, but the project plays normally then.

I suspect in that case that it is linked with your custom JS. Sorry, I am not a JS expert, my focus is on Captivate itself and all of its features.

In our case we found it was a browser plugin causing the issue. In our case the Angular DevTools extension.

Hi,

it could be a bug because I have exactly the same problem (just found out) and I am using the latest Captivate classic version 11.8.2.254. I have published several projects and uploaded them to the web. Important side information: I have not included any custom JS. When I run the projects, I get almost the same error messages in the console:
Uncaught SyntaxError: "[object Object Object]" is not a valid JSON
at JSON.parse (<anonymous>)
at eval (eval at e (CPXHRLoader.js:37:226), <anonymous>:1176:67)
As you can see, the error leads to the CPXHRLoader.js file, which is located in the "assets" subfolder of the project folder. The project plays normally, but it seems that the error slows down the loading process and partially causes the browser window to freeze, resulting in a poor user experience.
Could someone already fix this problem and help me further? Many thanks in advance!
