The task operations such as claiming a task using the REST API with container alias has worked with RHPAM (7.11) but not with the RHPAM (7.12) .

[Case 03259550]  - Unable to execute REST task claiming endpoint after upgrading RHPAM version to 7.12.
 
[DESCRIPTION]
 
The alias name is a single name used to link to different versions of a container. When
the container version is upgraded, the alias name will :

• Point to the newer version of the container when a new process is started.
• Interact with existing tasks and processes of a specific version.

Again, The customer is using more than one container and they don't want their client application to be changed with an updated container id.

Note:  The same claiming task endpoint was working with the RHPAM 7.11 version for a long time.
