Tested on my devapp.
Before the ec2_tags is:
ec2Tags={"Name": "dev-yaqinli", "devapp_version": "None", "service_mapping": "devapp", "usage_tag": "Dev Apps", "username": "yaqinli"}
Now the ec2_tags is:
ec2_tags: {"Name": "dev-yaqinli", "devapp_version": "None", "service_mapping": "devapp", "usage_tag": "Dev Apps", "username": "yaqinli", "availability_zone": "us-east-1d"}

can we update the info using availablityZone in PinRequest instead of using ec2 tags PingRequest(hostId=i-08211786ab8852f3c, hostName=helloworlddummyservice-server-u18-0a03fd62, hostIp=10.3.253.98, agentVersion=1.2.46-pinterest-1.0.2, autoscalingGroup=helloworlddummyservice-server-u18, availabilityZone=us-east-1e, stageType=latest, groups=['CMP',

On TAS side, we only handle the tags like this https://sourcegraph.pinadmin.com/github.com/pinterest/teletraan/-/blob/deploy-service/common/src/main/java/com/pinterest/deployservice/handler/PingHandler.java?L647:9
So, it is better to keep all ec2 tags in one place. Also, the tag name is availability_zone instead of availablityZone as you can see here:
