診断

There could be few reasons why issue collector might be showing this error. To investigate further, navigate to the project settings > Issues > Collectors and check for errors. If you notice the error below, this article is for you:

原因

By design, if a field is already Required in the Field Configuration and a new Issue Collector is created, the field will auto populate. Creating issue collector and afterward adding Required fields might cause a field to be missing from the Issue Collector view. 

Verifying the Field Configuration of the project, there are mandatory fields which are not added to the view of the Issue Collector. The configuration will prompt for that problem before saving it with the following warning:

Pro tip:

The quickest way to find the mandatory fields is by initiating a creation of a ticket from the same issue type from the Create button and look for the red * as in the image below:
