I am having trouble with confluence page auto-creation through Jira post function

[Jonathan Feagans]

I am attempting to set a post function when my issues in a Jira project transition to done, it creates a confluence page in my space. I have a two-way app link from the two servers using OAuth (impersonation) and also have a link set from the specific Jira project and specific confluence space as well. 

The script I am attempting to use came from here. https://www.scriptrunnerhq.com/inspiration/blog/how-to-create-a-confluence-page-from-a-jira-post-function

This is the error I am getting, everything I found about authentication was saying to switch from OAuth(not impersonating) to OAuth (impersonation). As stated I above that's how I have it set but am still having issues. This is the full error I am getting. Am I overlooking/missing something?
