Ovsdb Southbound Clustering Inconsistent output for sudo ovs-vsctl list bridge br-int

I do test Ovsdb Southbound Clustering with 3 nodes in CSIT. After connecting all the three instance nodes to the OVS using set manager, I tried to create a bridge using rest call, while forming the url with dynamic datapath id, i faced few issues.

First few tests able to get the output for the command sudo ovs-vsctl list bridge br-int and able to get the datapath id also

After few times, couldn't get the output for the command sudo ovs-vsctl list bridge br-int and it says an error as " ovs-vsctl: no row "br-int" in table Bridge " so couldn't create a bridge.
