Hi @yoavfr could you please take a look at the CI? Some of the test failed. Thanks!

The tests passed a couple days ago for my changes. Not sure what has changed.
If I understand the logs correctly - the failures are in TestVirtualNetworkeExpressRouteGatewayConnectionCRUD - "Breaking changes in the cmdlet 'New-AzVirtualNetworkSubnetConfig'". I haven't made any changes to this. Is the pipeline broken?

Looks like a merge conflict issue....

Hi @wyunchi-ms would appreciate if you could review before another conflicting commit causes failures again
