AttributeError: 'NoneType' object has no attribute 'POLLER' #326
Description
Python version: 3.12.5
hatchet-sdk version: 0.47.0
I'm on MacOS arm.
Have been getting this error following the workflow trigger examples from the documentation, but also see it using pretty much any method that communicates with my Hatchet instance:
from hatchet_sdk import Hatchet
hatchet = Hatchet()
workflowRuns = []
for i in range(10):
workflowRuns.append(
{
"workflow_name": "my_workflow",
"input": {"n": i},
"options": {
"additional_metadata": {
"bulk-trigger": str(i),
f"hello-{i}": f"earth-{i}"
},
},
}
)
workflowRunRefs = hatchet.admin.run_workflows(
workflowRuns,
)
Error:

The operation appears to succeed (I see the workflow runs in my Hatchet dashboard) but this would obviously break any downstream code I tried to implement. Any idea what might be going on here?
