BUILD: 78156
COMMIT: 6ef9f6c640a86180e92945b1e729ab11709cad3b

Preconditions:

1. 8.16.0 or above Kibana should be available.
2. Agent Policy should be created.
3. Two or more space should be created.

Steps to reproduce:

1. Log in to the Default Space.
2. Go to Agents Tab > Agent Policies Tab.
3. Select an agent policy and go to Settings.
4. Scroll down to the Spaces section and open the dropdown list.
5. Check that all created spaces are listed.
6. Select another space along with the default space.
7. Log in to the new space.
8. Observe that an error repeatedly occurs when assigning the created agent policy to the new space.

Expected Result:

• Error should not display on Assigning created Agent Policy to New Space.

Screen Shot

Whats not Working Fine

• Agents installed in newly created spaces are not visible under that space.
• A new agent added to an Agent Policy that includes both Default and Space2 is only visible in the Default Space.
