h3. Current Behavior

[| #current-behavior]

An exception is raised when using the wait_until_completion=False parameter on the sync version of client.branch.create.

h3. Expected Behavior

[| #expected-behavior]

Both of these should work:

from infrahub_sdk import InfrahubClient, InfrahubClientSync

client_sync = InfrahubClientSync()
client_sync.branch.create(branch_name="branchA", description="description", sync_with_git=False, wait_until_completion=False)

client = InfrahubClient()
await client.branch.create(branch_name="branchB", description="description", sync_with_git=False, wait_until_completion=False)

h3. Steps to Reproduce

[| #steps-to-reproduce]

When running this using the sync client we get an exception:

>>> from infrahub_sdk import InfrahubClientSync
>>>
>>> client_sync = InfrahubClientSync()
>>> client_sync.branch.create(branch_name="branchA", description="description", sync_with_git=False, wait_until_completion=False)
