Leaving a comment gives expression error and system error, Normal?

[55878965]

Old project opened in new 2024.4 AE.

Comments in expressions show up as error. Attached is the error notice. I have AE open in safe mode, error still pops up, but does crash AE when not in safe mode.

Without the actual code of the expressions this doesn't really mean much. If it's a legacy project that could basically be anything due to changes in the JavaScript engine and the reference to the comments could just be a fluke. Perhaps even some invisible stuff has crept in like an extra space somewhere or an unsupported character.

Hi @55878965,

Thank you for reporting this issue. Would you be able to share the project with us for investigation? And, to be clear, is After Effects crashing when opening the project?

The error "Object of type  found..." usually indicates an expression that ends in a function, which is not supported by the newer JavaScript expression engine. Try changing the expression engine to "Legacy ExtendScript" in the Project Settings (File > Project Settings > Expressions) and see if that fixes the expression errors.

Thank you for any additional information you can share,

- John, After Effects Engineering Team

Gotcha, it's a project from the learning course

Switching to Legacy did clear the "error".

Thank you
