Display/s fail to register when they are a member of a sync group with no leader

[Kent0425]

Description: If a registered display is a member of a sync group with no assigned lead display, re-registering that display display a 500 error.

Pre-requisite: 1. Display must be in the display list already; or 2. Display must be new and must be registered; then assign it to a new sync group as a member only

Steps: (For 1)

1. Create a new sync group; or find a sync group without lead display
2. Add registered display to that sync group
3. Re-register that display; check if there is error 500 in upon registering again (For 2)
4. Register display first
5. Create a new sync group; or find a sync group without lead display
6. Add registered display to that sync group
7. Re-register that display; check if there is error 500 in upon registering again

Do these steps recreate it?

1. Register a display
2. Ensure register is successful
3. Add the display to a sync group which does not have a leader
4. Register display fails?

There are two problems;

• You should not be able to remove a member if it is a lead
• If you do manage that (in some way) register should not fail

Register a display Ensure register is successful Add the display to a sync group which does not have a leader Register display fails?

Yes, we’ve tested this using Postman and you can reproduce the HTTP 500 error as follows:

• Register the display using XMDS / RegisterDisplay -> this should succeed.
• Add the display to a sync group that has no leader assigned ( Add a sync group and do not set a lead display)
• Try to register the display again -> you’ll see the HTTP 500 error.

We have not connected a real display to the CMS to see if its connecting as expected.
