Issue

When I try to create a Team master in Blue Ocean, I got the following error:

"Name this team - provided name is invalid!"

Environment

• CloudBees Core 2.150.2.3
• CloudBees Core on modern cloud platforms - Operations Center 2.150.2.3
• CloudBees Core on traditional platforms - Operations Center 2.150.2.3
• CloudBees Jenkins Enterprise - Operations Center 2.150.2.3
• CloudBees Jenkins Platform - Operations Center 2.150.2.3
• Blue Ocean Plugin 1.9.1+

Resolution

There is an incompatibility between Teams and versions of the Blue Ocean API higher than 1.9.1. This is currently being fixed and will be included in a future relase of the products.

Workaround

In order to solve the issue, you can follow different approaches:
* Use a Blue Ocean plugin version lower than 1.9.1
* Go to Manage Jenkins -> Configure Global Security and temporarily disable CSRF Protection.
* After that, you should be able to create a new Teams Master.

Important: Once the Team Master has been created you should re-enable CSRF Protection.
