We are having problems after upgrading the TFS Connector. We know it's using Ruby Gems.
Which Ruby Gems are we using?
To learn your current Ruby Gems version:
1. Open a command prompt window/terminal.
2. Browse to the folder where you are executing the TFS Connector.
3. Run the command: "gem list"
The output will list the components of your TFS Connector.
When upgrading to a new TFS Connector version you do need to run the "Install Gems" executable that's provided with the connector. That will upgrade/update your Ruby Gems version to match the version supported by the connector-instance you're deploying.
After running "Install Gems" you can run the "gem list" command again and confirm the listed versions match those in the release notes provided by CA.
