BigTable cluster update() requires location_id

[fm100]

https://cloud.google.com/python/docs/reference/bigtable/latest/cluster

This doc says that location_id is Creation Only, but it raises an exception when not given. Didn't have any problems with the code example below when using google-cloud-bigtable==1.7.3.

Environment details

• OS type and version:
• Python version: 3.11
• pip version: pip 24.0
• google-cloud-bigtable version: 2.23.0, 2.23.1

Steps to reproduce

1. Create the client
2. Create the instance with instance ID
3. Create the cluster with cluster ID
4. Set serve_nodes to change the node count
5. Update the cluster.
6. Fail

Code example

from google.cloud.bigtable import Client

project = "my-project"
instance_id = "my-bt-instance"
cluster_id = "my-bt-cluster"

client = Client(admin=True)
instance = client.instance(instance_id)
cluster = instance.cluster(cluster_id)
cluster.serve_nodes = 2
cluster.update()
