Issue Summary

Image content from the source field is not copied to the target field when a copy-field rule is used on a workflow’s Create transition in the new workflow editor. The target field displays “preview unavailable” after issue creation. The issue occurs because the system post function (Creates the issue originally) executes after the custom copy-field function, and the new editor does not allow reordering system functions.

Steps to Reproduce

1. Add a copy-field rule/function to a workflow Create transition in the new workflow editor.

1. Set the source field to a field containing images.

1. Publish the workflow and create an issue.

1. Observe the target field on the created issue.

Expected Results

The target field should display the copied images from the source field with the correct preview.

Actual Results

The target field shows “preview unavailable”, and images are not copied because the system post function (Creates the issue originally) runs after the custom copy-field function and cannot be moved in the new editor.

Workaround

Switch to the old workflow editor, adjust the post-function order so that the system function (Creates the issue originally) runs before the copy-field function, and publish the workflow. This is only a temporary option because the old editor will be sunset in early 2026.
