Unable to set issue type on uiModification plugin

Hello,
I’m having problems setting the priority/issue type field in my Forge uiModification plugin. I used the https://developer.atlassian.com/platform/forge/apis-reference/jira-api-bridge/uiModifications/ . According to the document, we can set the value of the issue type, but it shows an error.

. I tried other field methods, such as setOptionsVisibility, and they work.

So, is this an icon-related issue? or where can the exact error log be found? Any insights or suggestions on this would be greatly appreciated!
