Manipulate Customfields within Project Assignments with Power Automate

Happy Monday all, I’m having trouble with manipulating custom fields within Project Assignments. I have an PowerApp I’m developing that accesses MS Project and retrieves Project information, Task Fields, and Assignment fields from the Project Web Server. Problem is even though I can get the fields, I can’t seem to create or update them using Power Automate Flows. I’ve done a lot of research and found that you can do a lot of things with the Project Server REST Api. A lot of examples show that you can go to Project/Draft/Updatecustomfields. But again I’m trying to do this within Assignments. So I’m going to Project(‘ProjectID’)/Draft/Assignments(‘AssignmentID’) and trying from there. Course I’m checking out and checking in the project as part of the process. But I haven’t had much luck. I’ve tried just sending the update to the field directly which lead to the flow running without issue. But the field not updating. I’ve tried data dictionaries and get the “A Value without a type name was found and no expected type is available” error. I can give more details if anyone asks, but figure this would be a good start. Does anyone know what I’m doing wrong here? Thank you, Ryan S
