What are "estimator_pub" and "sampler_pub?"

[Seeker3005]

Environment

• Qiskit version: 2.4.1
• Python version: 3.12.3
• Operating system: Windows 11 Home

What is happening?

I am getting an error when running the "Close a Batch" sample code in "Run jobs in a batch" (https://quantum.cloud.ibm.com/docs/en/guides/run-jobs-batch) because "estimator_pub" and "sampler_pub" are not defined.

How can we reproduce the issue?

Run the following code in a Jupyter Notebook:
with Batch(backend=backend) as batch:
estimator = Estimator()
sampler = Sampler()
job1 = estimator.run([estimator_pub])
job2 = sampler.run([sampler_pub])

The batch is no longer accepting jobs but the submitted job will run to completion.

result = job1.result()
result2 = job2.result()

What should happen?

You get an error saying "NameError: name 'estimator_pub' is not defined."

Any suggestions?

I also get an additional error when trying to run the sample code for "Reconfigure jobs for parallel processing," where I run the following code and get "TypeError: PassManager.run() missing 1 required positional argument: 'circuits'":

from qiskit_ibm_runtime import SamplerV2 as Sampler, Batch
from qiskit.circuit.random import random_circuit
from qiskit.transpiler import PassManager as pm

max_circuits = 100
circuits = [pm.run(random_circuit(5, 5)) for _ in range(5 * max_circuits)]
for circuit in circuits:
circuit.measure_active()
all_partitioned_circuits = []
for i in range(0, len(circuits), max_circuits):
all_partitioned_circuits.append(circuits[i : i + max_circuits])
jobs = []
start_idx = 0

with Batch(backend=backend):
sampler = Sampler()
for partitioned_circuits in all_partitioned_circuits:
job = sampler.run(partitioned_circuits)
jobs.append(job)
