Description
There is a bug in the Jira rest client library, where calling the builder.setAssigneeName(assigneeName) in jira component doesn't work, as it seems the jira rest api (backend) evolved to not support setting the field with name attribute.

However it worked when setting the field with the account id attribute.
For a standalone server installation, using the name attribute works.
