Changes affecting workflow validators and post functions on the new issue transition experience

In my previous post, we announced the early access program to the new issue transition experience. Akin to the old experience, the new issue transition experience also supports variants of RichText fields such as the Description and Custom Paragraph (multiline text) fields. However, the new experience employs the REST v3 API for Issue Submit utilizing the ADF format, compared to the REST v2 API for Issue Submit utilizing Plain String format based on Wiki Markup. As a result of these format alterations, workflow validators and post functions relying on RichText fields are incapable of parsing the text from the ADF representation, leading to validation failures. Consequently, users may encounter difficulties in transitioning issues.
