SamplerV2 raises Error code 3211 with `ZZFeatureMap`

[t-imamichi]

Describe the bug SamplerV2 raises Error 3211 with ZZFeatureMap while it works fine with zz_feature_map qiskit-ibm-runtime 0.35.0 works fine too.

Steps to reproduce

from qiskit import __version__ as qiskit_version
from qiskit import generate_preset_pass_manager
from qiskit.circuit.library import ZZFeatureMap, zz_feature_map
from qiskit_ibm_runtime import QiskitRuntimeService, SamplerV2
from qiskit_ibm_runtime import __version__ as runtime_version

print(f"{qiskit_version=}")
print(f"{runtime_version=}")

service = QiskitRuntimeService(name="primitives")
backend = service.backend("test_eagle_us-east")

# qc = zz_feature_map(4, reps=1)  # OK
qc = ZZFeatureMap(4, reps=1)  # NG
qc.measure_all()
pm = generate_preset_pass_manager(optimization_level=2, backend=backend)
t_qc = pm.run(qc)
# print(t_qc.draw("text", idle_wires=False))
params = [1] * qc.num_parameters

sampler = SamplerV2(backend)
job = sampler.run([(t_qc, params)])
result = job.result()
print(result)

qiskit_version='1.4.2'
runtime_version='0.37.0'

Expected behavior No error.

Looks like this an issue with QPY - the error only happens after this PR where we set the minimum version to 13.

@mtreinish can this be handled on the Qiskit side?

just gave it a shot -- same behaviour with qiskit 2.0.0 ("RuntimeJobFailureError: 'Unable to retrieve job result. IndexError: list index out of range'")

Should be fixed once 2.1.0 is out and deployed server side. Tracking PR: https://github.com/Qiskit/qiskit/pull/13727

[kt474]

PR on the Qiskit side has been merged, the fix will be in Qiskit 2.1.
