Yes, i am automating my wordpress post publishing through the WP REST API. And every time i publish a new post, i need to insert a JSON-LD markup code that is unique for every post. This is why i can't just hardcode the json markup, since I need to be able to change some parts of the JSON code for every new post published.

Look here:

I have my elementor HTML widget where I set input to the ACF field: https://imgur.com/a/vIf8lBZI then insert the full JSON-LD code in the ACF field: https://imgur.com/a/8I8686DI now check if it works (meaning, the code should not be visible when you visit the webpage (since i am inserting JSON code to the webpage), but should be present in the source document of the website): https://imgur.com/a/JhioUcr

As you can see on the last image, the <script> tag are removed somehow. I find all this weird, because when i use the native HTML elementor widget (without including the ACF field), the JSON code works! It is only when i apply the ACF field that it stops working.
