Forums Adobe After Effects Expressions aerender and expression (JSON)

    I’ve created an expression for text title using:

    myData = footage(“data.json”).sourceData;


    It’s working when I see the preview, but when I try to render it using aerender then it shows default title.

    Is there anything that I need to do? precompile somehow?

    When I set text using expression then it’s not changing if I render comp using aerender:

    myData = footage(“data.json”).sourceData;


    If I render comp using After Effects then it’s displayed correctly.

    I use command:

    /Applications/Adobe\ After\ Effects\ 2020/aerender -project /Users/user/Desktop/test.aep -comp Insta_1080x1080_01 -output /Users/user/Desktop/

    Thanks for any help!

    I think you need to add your JSON file into your composition.
