There is a column called "Team Member" available in the New UI's "Tasks" tab. Due to a limitation in the number of characters that a particular cell can hold, tasks with large numbers of resources assigned against them, throw an error with code API-1019 in this tab.

This error in the UI is accompanied with an error such as the one reproduced below in the app-ca.log:

This issue has been logged as a defect with ID DE43682.
DE43682 has been addressed as of PPM 15.5.1.


Remove the 'Team Member' column from the Task list view. This can be done by expanding the Column Panel on the right hand side of the screen and deselecting the check box next to the 'Team Member' item. 
Additional Information:
Clicking on the conversation icon on the first column, for a particular task, will open a fly-out, that has a link to the "Staff" tab. This tab can be used to view all the team members on a task.
