IBM circuit function fails at level 3 only for simple circuit

[nonhermitian]

Steps to reproduce the problem

The following circuit / operator pair fails when using the IBM circuit function, but only at level 3, the others return a result:

g = Parameter('g')
g_vals = np.linspace(0, np.pi, 11)
op = SparsePauliOp('IZIIIII')

What is the current behavior?

Currently levels 1 and 2 work, but 3 throws an error:

'Traceback (most recent call last):\n File "/runner/runner.py", line 12, in run\n return func.run()\n ^^^^^^^^^^\n File "/runner/circuit_function/circuit_function.py", line 127, in run\n return job.result()\n ^^^^^^^^^^^^\n File "/usr/local/lib/python3.11/site-packages/qiskit_ibm_runtime/runtime_job_v2.py", line 138, in result\n raise RuntimeJobFailureError(f"Unable to retrieve job result. {error_message}")\nqiskit_ibm_runtime.exceptions.RuntimeJobFailureError: 'Unable to retrieve job result. Error code 1500; Internal error. -- Try again or contact support. -- https://ibm.biz/error_codes#1500\'\n'

Toggling between mitigation levels shows that this is not a device issue, but particular to this mitigation level

What is the expected behavior?

It should work
