Hi everyone… getting a ‘NoneType’ object has no attribute ‘inputs’ trying to execute a launch plan. the workflow doesn’t have inputs parameters. any ideas?
Copy code
from flytekit import Email, LaunchPlan
from flytekit.models.core.execution import WorkflowExecutionPhase
from flytekit.remote import FlyteRemote
from flytekit.configuration import Config

remote = FlyteRemote(
    config=Config.for_endpoint(endpoint="dns:///flyte.eks.tech"),
    default_project="flytesnacks",
    default_domain="development",
)

wf = remote.fetch_workflow(name="parent_workflows.workflows.example.my_wf", version="Mh7JCmzuS6MJr2XWw5ST-Q==", project="flytesnacks", domain="development")
print(wf) #prints correctly
lp = LaunchPlan.get_or_create(wf)
print(lp) #prints correctly
execution = remote.execute(lp, inputs={}, execution_name="test lanuch plan", wait=False) #fails here 'NoneType' object has no attribute 'inputs'
print(execution)
y

Related to this, the LP’s python_interface is none
