@nonhermitian are you still having this issue? Can you paste your code - wasn't able to replicate to issue

[renier]

I can recreate this issue with the following program using the main branch:

from qiskit_ibm_runtime import QiskitRuntimeService, Sampler, Session, Options
from qiskit.test.reference_circuits import ReferenceCircuits

service = QiskitRuntimeService()

session = Session(service=service, max_time=int(2.5*60*60))

sampler = Sampler(session=session, options=Options(backend="my_backend"))

job = sampler.run(ReferenceCircuits.bell())

print(job.job_id)
session.close()

It doesn't seem consistent, though.

It looks like the queue is returning 404 if the job that created the session is still running. Opening an issue with that team.
