When creating a project in WorldServer Transport, I cannot add reference files to an existing project. Error 'No rights to WRITE for resource type ATTRIBUTE_VALUE(ATTRIBUTE_VALUE - > WRITE(CHANGE_ATTRIBUTES. CHANGE_PROJECT_ATTRIBUTES)'

When creating a project in WorldServer Transport, I cannot add reference files to an existing project. I see an error as below:

No rights to WRITE for resource type ATTRIBUTE_VALUE(ATTRIBUTE_VALUE - > WRITE(CHANGE_ATTRIBUTES. CHANGE_PROJECT_ATTRIBUTES)



In a german UI, the error displays as: 

Keine Rechte WRITE für die Art der Quelle ATTRIBUTE_VALUE (ATRIBUTE_VALUE -> WRITE [CHANGE_ATTRIBUTES, CHANGE_PROJECT_ATTRIBUTES])

As a WorldServer Administrator, make sure that these permissions are enabled in the Transport User Type (or whatever User Type the user who receives the error is associated with):

1- REST API & New UI > Attributes > Can read all attributes
2- REST API & New UI > Attributes > Can update all attributes

These two options can also be enabled, but are not needed to be able to upload attribute files during project creation:

1- Transport >Can update project due dates
2- Transport > Can update custom project attributes

Workaround in version before 11.4.x:

In WorldServer versions where the Hotfix is not available, the workaround for a Transport User encountering this error is:

1. Ignore the error during project creation and create the project anyway by clicking Finish.
2. Once the project is created and visible under your list of Active projects in Transport, click on it to open it.
3. In the Reference Files section, browse to your reference file and click Add to add it. No error will appear. 
4. Finally, click Save. 

The User Type permissions need to be adapted.

Refer to this article describing a similar problem with a slightly different scenario:

As a Transport User, I cannot add reference files to an existing project because I am asked to change the project due date
