As I suspected this didn't get much traction in the devlopment queue.
Because it was reported quite a long time ago, I thought I'd better start from scratch with a clean test site and current plugin versions to verify that the problem still occurs.
But I can no longer reproduce the problem, it works as intended without error.
I have a site with current Types, Gravity Forms 2.4.18, Elementor 2.9.12 and Elementor Pro 2.9.5.
I made a couple of simple Gravity Forms (just with a text field and the submit button).
I have a custom post type with a WYSIWYG custom field.
I published a post and in the WYSIWYG field inserted the shortcode for one of the Gravity forms.
I used Elementor Pro to make a template for the posts of this type.
I added a Text Module to the template and inserted a types shortcode to output the WYSIWYG custom field value.
I loaded a post on the front end and the specified form was loaded, and there were no errors.
I also tried submitting the form, and that worked.
So, the issue doesn't seem to be reproducible with the current plugin versions, and I propose to mark this as resolved.
Sarah, if you find that you still have problems after updating all of the plugins and confirming the above testing steps then please open a new thread and provide the specific steps that are required to reproduce the problem, and be sure to reference this ticket.
