HI Partner
Try following the mentioned steps to mitigate this Error:
1. The error might looks like this.
2. Scroll down to download the log file.
3. In the log file locate what function is not working and what file it is coming from. Use the following as a template. We can see collapseProcessControl is the function that seems to cause an issue and it comes from the ProjectInitialization script file.
4. Navigate to Settings > Customizations > Customize the System
5. Open the Entity for the record where you got the issue and open the form where you got the issue. In this example, it is Project and the Main Form.
6. In the Form, open the Form Properties
7. Locate the function in the Event handlers. In this case, there is a duplicate. Remove one of them and continue to the next step when you only have one of them. If you cannot find your function, change the option in the Control / Event dropdowns.
8. Open the function by double clicking on it. You should get something like this.
9. Ensure Pass execution context as first parameter is checked.
10. Press Ok.
11. Save
12. Publish.
